I don't know what rock you've been under, but just this week Facebook has been accused of illegal collusion with Google[1] *and* illegally ignoring competition authorities when completing its Giphy acquisition.

All it takes is them going, 'hey this administration is going to get in the way of a revenue stream, we've been getting good money to facilitate what some customers want' (i.e. revolution, genocide, etc)
And then 'we should make ourselves available to these groups, to disrupt the administration that might hold us accountable. If they get hurt, so what? They are against us'
Look back to Cambridge Analytica. Facebook can serve to overthrow the government… any government… if their influence is profound enough. They've got control and have done studies on what they're able to do, and it's not unthinkable that they are doubling down rather than be brought to account. They rightly see themselves as a key player here. They're the megaphone to be used by state powers and revolutionists, in many countries including at home.
My gut reaction is that this is really the tip of the iceberg, and what they're really up to is on a very large scope. If you found you had the Panopticon and could swing any election, flip any issue, what would you do?
Then consider it's Mark, in sole control of all this, and the same guy he's been all this time. I don't think he delights in destroying people. But the guy is purely self-interested and is just being a paper clip maximizer, the paper clips being 'power as he has been able to wield it'.
