There is more ot it than just the monopolies crushing new competition and small firms in their space. The gatekeeper role for information that Google and other tech monopolies have is a danger for democracy in a way that the Rockefeller's monopoly of the oil business by Standard Oil never was at the turn of the previous century. TR took up the role of government ensuring that fair competition exists by breaking up the monopolies in the oil business at that time. Today this is left to the courts and they take far too long and come up with decisions that do not address the main probem points brought up by the US Justice Department. Judge Mehta after 5 years did little to address the problems of tech monopolies and it is now left to other remedies and other leadership to come up with ways to break up these monopolies.
