There's no "better" alternative really - if Facebook censors content - which it absolutely does and which it will be forced to do by politicians even if they didn't want to - then Facebook is also responsible for these censorship decisions. Making a sock puppet to deflect responsibility is a transparent move that is not going to fool anybody. It makes situation slightly worse as it insults the intelligence of the community by implying this transparent trick could work, but otherwise everything stays the same.

In theory, Facebook could figure out a way to have truly independent panel of experts than are non-partisan and aren't beholden to Facebook in any way, but I have no idea how they could do it in practice, and even if they did, it'd backfire on them very quickly as soon as that panel would make a decision that some activist group wouldn't like, as those activists would surely target Facebook and Facebook would have a choice to either annihilate the credibility of the panel by ignoring its decision or face the wrath of activists which the Facebook have proven many times in the past they can't withstand and will have to cave anyway.

So I really don't see any positive outcome here. Once you're in the censorship game, you're in the censorship game, with all that involves.
