I think the way the actual sausage is made is that they don't care who they platform. They'll deplatform anyone if enough people make enough noise and threaten their bottom line, but no one makes enough noise about Taliban terrorists or the Burmese military to threaten them politically.

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.
