As I wrote Friday, Twitter's banning of links to competing social platforms *could* be perceived as anticompetitive, according to antitrust experts including Bill Baer, the former DOJ and FTC antitrust chief in two US administrations. But it isn't exactly cut and dry, they tell me.

The tricky thing is first proving that Twitter has market power. https://www.cnn.com/2022/12/16/tech/mastodon-twitter-links/index.html

@b_fung @emilybell hence why he pretended to ban a larger number of social sites, ie Facebook & Instagram. To be able to say the market is larger?
