One funny thing about it is that it's not bundled with the Office suite the way Word, Excel, Powerpoint and sometimes Access are. Teams is part of your "Microsoft 365" subscription, which could include your rights to the Office suite, Exchange Online email service, etc. So within the ecosystem Teams isn't part of the Office package, it just works with it, sort of.
That's part of what makes the anti-competition claim hold true to me. If Teams were pushed as a first-class component of Office to paying users (maybe the way Groove was at one point) but not forced upon every user regardless, it might be different.
