..but they don't leverage their MS Office dominance to harm the market. You can access MS Office with the open HTTP(S) standard. MS Office works on Windows, macOS, iOS, Android, and in WINE. It follows the OOXML standard which you can open in LibreOffice as well.

Apple -> These $%^&ers don't allow anyone to repair their own devices, they don't allow a different distribution method on iOS/iPodOS devices hence quickly evolve to unfair market advantage.

Amazon -> Undercut anyone at any cost while having the worst review system on our planet.

Facebook -> RIP privacy, just see the recent scandals.

Google -> Probably something involving Android...

Microsoft? Oh I can write a book about my terrible experiences with that company. I hated this company and everything it stood for for about 15+ years or so (at least 1995-2010). Recently though? Not so much.

Is that still true? I’m guessing Google Docs has a non-trivial marketshare. Probably not bigger than MS but real competition.

The EU discussed forcing Microsoft to open up the Office document formats as part of the antitrust remedies they enforced against Microsoft (in the same way that they forced Microsoft to open up the protocols used for Windows Server to communicate with Windows clients), but ultimately they did not do so.

True , but i can't think of a way in which they used this dominance against others lately. Antitrust action aims to fix competition, and they won't do it if they think it's not broken.

Google Docs is pretty big, too.
