I don't want Chrome or Firefox or any browser to be the OS, I don't want 99% of the gimmicks that are getting added. I can barely tolerate an OS being the OS given how they are steadily moving to less and less actual control and towards knowing best (Windows updates, iOS turning bluetooth off "until tomorrow" etc etc).
Just in case I'm becoming too old to be relevant, neither do my kids and their friends as far as I can see. if anything they're far more simplistic than me - YT, browsing, and a few chat and social apps. So presumably all this junk is for adtech and tracking, for sites to hassle us on yet another device.
Of my friends who work in tech, none of them seem to much like the monster they helped create any more.
