Jake Archibald writes in his blog about the bigger problem presented by importing third-party content into web pages. Even CSS is a problem as a CSS keylogger demo showed the other day.

A few days ago there was a lot of chatter about a 'keylogger' built in CSS.

Some folks called for browsers to 'fix' it. Some folks dug a bit deeper and saw that it only affected sites built in React-like frameworks, and pointed the finger at React. But the real problem is thinking that third party content is 'safe'.

While most are acutely aware, yet ignore, the danger presentd by third-party javascript and javascript in general, most forget about CSS. Jake reminds us and walks through quite a few exampled of how CSS can be misused by third-parties exporting it.

    what not-broken revenue model would you prefer?

    None.

    Maybe you consider that "broken", but the web was a lot better before all the fast-buck artists showed up.

    People who thought they had something worth saying paid a few bucks a year for web hosting to get their message out, or share their software, or whatever they'd created that seemed worthwhile to them. Participants in this "sharing economy" invariably got a thousand times more out than they put in, and the freeloaders weren't much of a burden.

    Then a billion assholes showed up, all thinking "how can I get rich from other people's work?" and it has plummeted downhill like a rocket-powered bobsled ever since.

    Our big mistake was making it easy for idiots. We need to return to the days when a little technical knowledge was required as a small barrier to entry.

    A return from a commercially dominated web to a hobbyist-dominated web would decrease the demand among viewers for Internet access, which would in turn make it no longer economical for your ISP or its competitors in your area (if any) to continue to offer high-speed Internet access at an affordable rate.

      You don't need high speed when a page is only 40K. And it was not only affordable, you had many providers to choose from, which kept prices down and service up.

        Though dial-up was competitive, you did need a POTS line, and many households have long since given that up in favor of a cellphone.

        How would amateur video be transmitted over such an infrastructure? Mail order DVD+R?
