We have all heard ad nauseam about Windows 10 "telemetry" features. Most of us don't like them and avoid the OS or neuter it as much as we can. Now, the question arises, what about other OSes? How about Android and what it specifically does that we don't like with regards to our privacy and how do we adjust it? How about OSX? Anything wrong with Apple's OS that you modify? And iOS, the least flexible OS of all? Finally, we come to Linux; apart from Ubuntu's Amazon fling, any other distro doing something that smells bad? Feel free to toss in other OSes, as well. Let it rip.
