Does deliberately crashing Windows when your software is detected count? Microsoft were accused of doing this to DR-DOS. Alas, as part of a settlement, Microsoft paid DR's successor $150 million and in return they destroyed all evidence of Microsoft's actions thus making it impossible for Microsoft to be effectively prosecuted for their behaviour.
No, but occasionally they chose to create a detailed duplicate of your app and give it away for free, especially if you had turned down a buy out offer.
You run Windows applications locally and no-one but you has control about what you do with your Windows installation (mostly). Microsoft simply could not pull applications even if they wanted to.
Embrace your freedom by utilising it. Consider how the future might look like if everything is "in the cloud", remote and you are at the provider's grace to be allowed to access your tools and data.

There was something about Windows Media player being able to revoke a local media file that was in breach of whatever the rule for the day was, wasn't there? Sorry about being vague but it's years since I was in Microsoft land. But yeah, this kind of stuff by Facebook surprises me not in the slightest. As a software company, would you be bothered getting into the compliance game? That's like being a software house and a cop shop.
