Glenn Greenwald covered this pretty well. The establishment isnt going after Facebook because they are against it's censorship or monopolistic practices, they want to coopt Facebook's censorship, monopoly and agenda setting ability for themselves.

Zuckerberg may have benefitted from Jewish connections in his takeover of Facebook and it's rise, but he's never struck me as particularly into being Jewish, and this combined with his placement of profits and Facebooks growth over Jewish propaganda and censorship likely put him on their shitlist. Zuckerberg knows their is a huge untapped market for whites sick of the woke agenda and he's been somewhat reluctant to ditch that just to push the Tribe's agenda and they dont like that at all. That's my impression anyway
