Why do we want to heavily regulate or even break up Big Tech, exactly?

It wasn't long into my reading of last weekend's Wall Street Journal essay "Can the Tech Giants Be Stopped?" that I realized the author must be the same one who wrote "Is It Time to Break Up Google?" back in the New York Times last April. Indeed, the writer of both is Jonathan Taplin, director emeritus of the Annenberg Innovation Lab at the University of Southern California. I found that first essay sort of odd because I really didn't discover a strong argument for government action. Oh, Taplin made some assertions and declarations such as "It is impossible to deny that Facebook, Google and Amazon have stymied innovation on a broad scale" and that we need to stop "pretending that unfettered monoliths don’t inflict damage on our privacy and democracy."
