Saying that Facebook has an impenetrable competitive position when they aren't even the dominant social network for young people anymore, and haven't been for years. They made a good deal with Instagram but that hasn't stopped innovation in the space at all. What is particularly unfortunate is that Facebook are in the firing line because they became the lightning rod for politicians...and there are actually companies out there doing anti-competitive things. Google has bought up digital advertising, they have a piece of all parts of the value chain...how is this legal? Apple and Google have sewn up the market for apps? Nothing. Also, Facebook has been the most responsive to politicians but the fatality was being seen to have helped Trump in 2016 (even though they didn't do so as actively as they helped Obama). FB are terribly rapacious but you feel bad for them in that there is literally no way for them to win (I suspect the core social network will eventually get spun off as it gets overwhelmed by govt claims against it).
