I don't know about openly hostile. Definitely making moves that the user base openly disagree with and think are, at best, very bad decisions, but I don't think they have crossed the "hostile" line. And MS is not alone with those kinds of decisions.
Apple may not "force" you to use an iCloud account for their devices, but they sure push it hard.
As far as Linux communities go, Red Hat, Arch, Cisco, and even Ubuntu have also done their fair share of "bad decisions".
everybody else is doing it doesnt excuse the issue.
when users make a technical effort to workaround these bad decisions, and you keep chasing after them, subverting said technical measures, in order to enforce said bad decisions, this has gone far beyond being bad decisions; it is being done on purpose to prevent users from opting out of a Hostile ecosystem.
What would it take for you to admit they are openly hostile? Removing the ability to install without internet, taking up resources on your computer by stuffing more and more forced ai onto you that nobody asked for, resetting default browser preferences, taking screenshots of everything you do, baiting people into uploading their private files onto the cloud through onedrive, and this is still not enough? You still go "oh I don't know about openly hostile?? Hello???
