When I hear big tech companies say, “we’d love government regulation” what I hear is something similar to what Jonathan points out. That monopolist regulation that makes it even more difficult for new or existing companies to compete, further entrenching these big companies.

the focus should be less on the global ambitions of these technology companies and more on the practices they’ve enacted to stifle competition.

We’ll see if congress can keep their eye on the ball, but I wouldn’t hold my breath.
