The corrective force should be market competition, but Google is a monopoly not a monopoly with so many moats it might as well be a monopoly.

They also buy up the competition before it gets a chance as is the way now.

Why should be? I think it is abundantly clear by now that market competition alone will not fix this. Though that does not stop people from claiming "Yes that failed and people suffered/died, but that was not real capitalism! If only we had a real free market, it would have been better!"
