FB is a direct competitor to media brands -- eyeball time that would have gone to CNN or WashPo or MTV now go to FB. FB then resells those eyeballs to said media brands, and it's big enough to command market power--it can control prices and terms and it's so huge you can't easily take your budget to a competing service. (It has in fact done this, before the wave of "FB is evil" stories, there was a wave of "FB is raising the price of impressions" stories. So many media brands perceive it as an existential threat. FB did some fairly dirty things to obtain its huge market share and it's too powerful. So I don't really see a problem with all its competitors piling up on it, but that's definitely what's going on.
