If lawsuits and not supporting something you like makes you dislike a company, I'd guess that almost all corporations would be on your 'hate' list.
My dislike of MS is quite simple. I simply don't like their products. That doesn't mean I automatically love OSX or Linux. IMO OSX is a mediocre product with a polished user experience and Linux as a desktop is just broken. Unfortunately, I can't say there is a single OS that I like at the moment.

This is a popular position, yes. But Microsoft in particular have tried to make Linux impossible on a number of occasions over a period of decades, so it'll take a while for the guerillas to come out of the jungle and stop fighting them.
But now they're in competition with the platform that want to annex all your personal data and the platform that want a veto over all applications, so they're not necessarily the most hated party in the room any more.
Linux survived because commercial vendors poured in over a billion dollars into making it a viable UNIX alternative. Microsoft's feeble attempts to sabotage it are pretty much irrelevant in that regard.
It's easy to call it "feeble" because it lost, but the worst-case outcome would have ruled the POSIX API was copyright SCO (funded by Microsoft), making it infringement to distribute Linux.
Linux could have survived in peaceful co-existence without the corporate billion. It would have been smaller and more hobbyist. It could not have survived if all the judgements had gone the wrong way.
