I fail to see how Windows is not the epitome of user abuse, granted I only occasionally have to use it nowadays so might be off. For starters migrating users to Windows 10 via dark UIs and even forced upgrades. Generally abusing the update channel and forcing updates users be damned. Enabling and re-enabling telemetry. Adding and re-adding Microsoft services people did not ask for. Ads in the Windows start menu. Intercepting installation of Firefox/Chrome.

In other news Microsoft just recently extended GitHub with certifications after embracing it https://news.ycombinator.com/item?id=24855453

Personally I also dislike their sales tactics, at uni I had my fair share of Sponsored by MS classes, using .NET and Visual Studio.

Just search for Microsoft at the bottom of this page really.
