I would propose a new law of interaction design: Whenever something is promoted as a tool that you wouldn't need to learn, then it's actually designed to use you, and you are the tool.

If all the crap that people suffer through, and make YouTube channels dedicated to about how much Windows is hell, is not enough to get them to look elsewhere then "fixing" other operating systems won't get them to look.

They aren't looking and they aren't interested in looking. At this point they have no one else to blame.

I don't know how to better explain this, but as I get older I find I just have less energy to address all the things. My worldview gets larger and my energy levels become less and eventually I need to just 'stop' progressing in a certain activity. It could be re-learning the TV's remote control like my grandparents, or it could be re-learning how to drive with an EV touchscreen on modern cars, or it could be re-learning an operating system that just presents a mountain where you just say: "I can't do it this time."

The vast majority of people do not test out alternatives to things they just need to use for work, they don't lobby their government even informally for different laws, have never gone to small claims court (or even been in a court room when it's in session). These are all minority "activist" activities for lack of a better word.

The tin foil hat interpretation of this is that it is all by design, by whatever cabal runs everything, to subjugate the masses and control them directly or indirectly. The generous interpretation is closer to an extreme version of Sturgeon's Law[0] where this is just a natural, even inevitable, byproduct of most things being garbage. Like most things the truth is almost certainly somewhere in the middle.
