I mean, I don't like Meta at all, but what do you expect? If you want to run a full-page in the New York Times that criticizes the New York Times, they're going to refuse to run it as well. Private companies generally don't publish things that run counter to their interests.

It would certainly be interesting if we wanted legislation to force private companies who provide paid ad space to publish ads that paid the most regardless of the content, but then that opens up a whole other can of worms. What if the ad offering the most money is racist and horrible, or disgustingly obscene? At that point you start needing the government to decide what is allowed to be banned and what isn't, and then it's meddling in speech which is prohibited by the first amendment.

So this just seems like an obvious non-story to me. Of course Meta is removing these ads, because pretty much any advertising platform would do the same about ads that criticized it.
