Facebook has enough momentum that not having the best and brightest probably wouldn't slow them down. And, let's face it, for what Facebook pays, there are still plenty of skilled people who don't favor one side or the other who would happily take their money.

Momentum would keep them going for a long time but they’d eventually stagnate if they lost the majority of their best workers – look at other once dominant tech companies who can longer get the best talent, even with their deep pockets. This doesn’t mean they’d collapse completely of course.

I realise this is just a hypothetical though – highly unlikely since it would require the top employees leaving en masse.
