MS's bottom line doesn't depend on how happy users are with W11, especially not power users like ourselves. W11 is just a means of selling subscriptions (office, ai, etc). The question isn't 'are users happy' it's 'will OEMs and business continue to push it?'. The answer to that is almost certainly yes. OEMs aren't going to be selling most pcs with ubuntu included any time soon. Businesses are not going to support libreoffice when MS office is the established standard.
Maybe apple could make inroads here, but they don't seem willing to give up their profit margins on overpriced hardware, and I don't think I've ever seen them release anything 'office' related that was anywhere near feature parity with MSO, and especially not cross platform.
