Funny how that election turned out.
I don't think we need to break up any of these companies. Particularly when an industry like Cable/ISP's exist, which are allowed to have an actual regional monopoly and artificially inflate prices in order to force you to use their other services.
None of these three do anything of the sort. And Amazon, really?
EDIT> Aspirational fiction, perhaps.
Also, do you expect people to name names of lobbyists? I think it's pretty safe to assume there are groups who feel that the FAANG companies are too powerful and need to go the way of Bell labs. And many people (wrongly? rightly?) label anything they feel is politically motivated speech as "propaganda".
