Like everyone using chrome and allowing Google to control the browser ecosystem? Or Samsung and get all that delicious unremovable bloatware on their phone? Every company makes these decisions because rich people who invest in them force them to make profit year over year or get sued. This is a flaw in capitalism.
Yes and we should scold Apple, Google and Samsung and consorts for their behavior. And also educate their users that are seemingly unaware of the shit that is going down.
You should look into the GrapheneOS installation process. It's actually pretty easy, you can flash it from the web browser. I had a slight problem during install, so I hopped into their matrix room and someone said "try a different cable" and it worked, simple as. The process was pretty well documented, other than my bad cable all I had to do was follow the prompts, and the good cable was the one that came with the pixel, so just use that and you're gold, you can even flash it from a different android phone's browser instead of a PC, they really couldn't make it any easier.
