Also Microsoft's dominance rarely starts with evil moustache twirlers that want to "embrace, extend, extinguish".
Sometimes that's where it ends up, but that's not usually where it starts.
Usually it starts with rank-and-file Microsoft employees saying, "I want to build the next big thing!"
So they do.
But how do they build it? With Microsoft "integrations".
Then the executives get involved, and they naturally want to monetize...
Most people who work at Big Tech companies don't wake up in the morning and think to themselves, "How do I wreck the Fediverse?"
Instead, they go, "I want to build something that I genuinely care about -- and I have the financial resources to do it!"
So they do because why not, right?
Where it gets dodgy is when the bean counters start asking, "How do we decrease churn?"
