Or they have already implemented them cause they consider those measures to be important / effective. Recommending something you don't think is worth the effort would be stupid, just like not implementing good ones. If FB decides against adopting some measure, they obviously will use the same arguments for not recommending it. As for FB recommending lower standards to govern the competition... would anyone here actually do this unless part of a brand? Evaluating recommendations is a politicians job, and I'd expect them to listen to more than just the few biggest companies.
