Facebook wants more power to censor ordinary people while platforming literal terrorists(Taliban associates, Iran proxies etc) at the same time.
I don't think they're even trying to consolidate power. They appear to be in the very unenviable position of hosting half the internet's public verbal diarrhea, with no freakin clue how to deal with it. No sympathy here for the devil, but this is basically inevitable whenever anyone tries to grab the brass ring and take over a totally chaotic system.
Facebook is essentially a failed state.
