On March 31st new rules take effect in China banning VPNs and cross-border leased lines. Bloomberg writes:
Censors have already eliminated hundreds of VPNs, which route user requests for sites through virtual networks located on the providers' servers, disguising their users' true locations or destinations. A few operators have been jailed, and over the summer Apple Inc. began removing VPN software from the Chinese version of its App Store. VyprVPN, ExpressVPN, NordVPN, and a shrinking number of others are still working to outpace the government, renting extra cloud servers from Amazon Web Services Inc. and the like to buoy their networks. They're also working on software that can make user activity look like permitted internet traffic, sometimes by renting internet protocol addresses that have also been used by government-approved services.

"Back of the Moon" from whose point of view? And the Earth can reflect light, the Earth's atmosphere can refract it.
What protuberances? You are making assumptions and not telling us what those are. I find your remarkable lack of ability to make precise and descriptive statements telling. What I see however is a round shadow from start to finish like the popular theory of a round Earth casting a shadow on a round Moon would predict.
What's particularly silly about this whole thing, is that you are quibbling about slight, probably imaginary differences in perception. And in turn, you don't mention any alternate explanations.

The Sun brightens to the summer solstice, and weakens to the winter solstice.
You are taught in school that the Sun 'moving South'(aka The Tilt) for the winter accounts for the change of seasons. But have you modeled it yourself? For if you did, you would discover that the Sun rising from the East is no different across a globe as the Sun rising from the South-East. The horizon is the horizon, in every direction. It is an inherent property of a sphere.
So what really causes the change in Sun light, color, brightness, and heat across the seasons? And remember, any answer involving the atmosphere will inherently need to show the same pattern of change from morning to night as you would claim for winter to summer.
If you think this question makes no sense or is foolish, you haven't grasped the question.

WTF? Of course we've modeled it every school child has.
The sun rising in the east vs rising in the south-east is important with respect to the seasons not because of the angle from which the sun rises but the arc it traces through the sky.
In the summer, for the sake of this argument, rises in the east, crosses high overhead, and sets in the west.
If in winter it simply rose in the south east, crossed overhead, and set in the north west then your argument would make some semblance of sense.
But that isn't what happens, in the winter, it rises in the south east, its highest point is not as high overhead but somewhat more the south, and then it sets in the southwest. Thus we get shorter days; and due to the lower angle the sunlight received throught the day is more oblique so the energy is spread over more area. (ie less energy received per square meter). Hence seasonal differences.

for khallow: yes yes yes. You've also missed the question.
For both: How can the sun behave differently from horizon (0 degrees) to azimuth in winter(say, 30 degrees) in winter, but not have exactly the same behavior in summer from 0 degrees to 30 degrees?

Assuming the sun actually does look differently (it certainly doesn't behave differently, as the sun we see on the northern hemisphere is the exact same sun seen at the same timeat the southern hemisphere, where there is summer at the same time!), I'd guess it is an effect of the absolute humidity of the air: In winter, the absolute humidity is lower (because the air is colder, it cannot "hold" as much water as when warm). If the water vapour significantly affects the scattering of visible light in the atmosphere (I'm too lazy to check, but it seems reasonable), then the sun light in winter should have a different intensity (and possibly also a different spectrum) than in summer. In particular, since water is known to absorb red light, I'd guess the sun light would have relatively more blue in winter, which makes if look "colder" (note that this is an interpretation by our visual system; actually the blue light is the one with the most energy).

Atmosphere of course. I'll note that one can see this with heavy smoke in the air. For example, I work in Yellowstone National Park. At times, the park experiences heavy smoke up to high altitudes due to smoke that came from fires hundreds of miles upwind from us. As a result, I've seen a shift at all times of the day, including sunrise and sunset to redder sunlight in those situations.

It doesn't. Your question is broken. What does change, for example, is how long it takes for the Sun to reach that point. In winter during the corresponding winter solstice for that location, it takes half your daylight hours to reach that point. 30 degree peak azimuth in winter means the location is at a latitude of roughly 36.5 degrees [arizona.edu]. For example, cities near that latitude [wikipedia.org] in the northern hemisphere would be Tunis and Virginia Beach or Auckland in the southern hemisphere. Glancing at day length [orchidculture.com] tables, I get almost 5 hours to make the trip for the Sun in wintertime.
Summer solstice would have the Sun passing overhead at a peak azimuth of 77 degrees and take a little over 7 hours (7.3) to get there from sunrise. The Sun traces a partial circle as its path, so it'll rise faster in the morning than when it is near 77 degrees. So I can overestimate the time it takes to reach 30 degrees by calculating 30/77*7.3 = 2.8 hours.
So in other words, same Sun, same azimuth, but it crudely takes a bit over half as long to get to the same azimuth in the longest day in summer as it did the shortest day in winter.
And notice the power of the model. I can tell you with a few internet look ups where the Sun will achieve this geometric configuration, how long it'll be in either case, and that the feat will be equivalent in northern or southern hemisphere at the same latitude.
Further, this readily explains the greater heating of Earth in summer versus winter. The higher the azimuth of the Sun, the more directly it shines on the land. Oblique angles (low azimuth) mean that the same sunlight is spread over a greater amount of land. One can see that by taking a sheet of paper, positioning it so that it intercepts the most sunlight (that is, it is perpendicular to the sunlight coming in), and then looking at the area of the shadow it casts. When positioned this way, the amount of sunlight tends to be very close to constant (with the variation being how much sunlight is intercepted by the atmosphere). At very oblique angles, such as around sunrise and sunset, it means that the shadow is very long, indicating that the fixed amount of sunlight which hits that piece of paper is spread out over a lot of ground. Meanwhile, the shadow at noon is far more squat indicating a much higher heating per unit area of the ground.

What exactly needs to be modeled? We know for example that the Sun is lower in the sky (azimuth angle) and stays above the horizon for less time in the winter than it does in the summer in the northern hemisphere. Thus, it heats less as expected (sunlight at an angle to the ground is going to result in less heating energy per unit area of ground even before the reduced length of a winter day). At night the stars circle around Polaris, the north star which I've seen at lower and higher azimuth angles corresponding to how far north I am.
Such as the day cooling in the late afternoon as the Sun sinks to the horizon? And of course sunrise and sunset have different colors due to sunlight passing through more atmosphere and dust. That box is checked.

There is nothing wrong with the movements. The problem is how the Sun can behave differently at different times of the year when compared at identical angles above the horizon. Angles of sunlight, time above horizon, and resultant heating is distraction. The heat and light at a given point in the sky in winter vs summer is the purpose here.
