If this was a political move from the establishment, the game just changed fundamentally, at least for us internet denizens.
Big Tech was operating under the impression that as long as they let bits of the right get slowly run down by restrictive moderation, they'd be otherwise left to their data harvesting fiefdoms, and allowed to continue their manipulation, and by extension their ridiculous profits. If the establishment just actively assaulted one of the big players, the pact is broken. As soon as it becomes objectively more dangerous to let the establishment hold power and suppression of dissent than to side with them, you'll see a free speech swing or suddenly the algorithms promoting inconvenient data for the establishment. The conservatives won't really come back, but if they can redpill the NPC's hard and fast enough, the establishment might break under the pressure before facebook does, and then they can try and salvage what remains. It would amount to little more than a suicide pact.
That being said, this is an extremely unlikely move for the establishment to make. They are dependent on their suppressive propaganda machine, and they've used it recently for the hunter laptop, so its not like they've forgotten its importance. They have very little to gain by sieging facebook, and stand to lose the entire foundation of their citadel of lies.
And its unlikely Zucc had a change of heart - There's no more profit in flipping to the other side, they've already ruined that audience. The deplatformed will not easily or willingly return to your platform. For better or for Worse, Facebooks only option is keep sailing or double down, there's no room to step back.
