> It's hilarious the irrational hate Microsoft gets when they are objectively not that bad.

There's no hate going on, irrational or otherwise. They have been really bad, and Teams vs Slack is a good example of how they are still bad in some instances. Not illegal bad, although maybe that, but just bad for competition, kept in place not by evergreen product quality (unlike Apple) but by 100 million IT departments all with mouse-only skills who couldn't choose anything but Microsoft without putting themselves out of a job.
