I don't understand this movement at all. It seems very, very short sighted and also misdirected. The most toxic marketplace and social elements of some of these companies is their business model, not their scale/size. Breaking them up into pieces doesn't fix their deleterious business models and only opens the door for non-US entities who remain scaled/vertically-integrated to become the dominant forces in the market. Either that or this will necessitate passing future protectionist legislation to keep out foreign competition, which I'm both skeptical is actually a good idea in general or that the US has the actual resolve to do so. What problem is supposed to be solved by breaking these companies up? It doesn't make any sense to me, and I say this as someone who is generally deeply disturbed by much of what is enabled by some of these firms, so this isn't an endorsement of these companies. It's an indictment of the approach.
