People want the great monopolists regulated because they act like monopolists.
People want the giant companies to pay taxes, because they want them to pay a fair share and because it's unfair they get away with not paying taxes while competing with small companies that do pay taxes.
People realise that the giant companies create few jobs, often terrible ones as temps, but destroy many jobs. People are not sure the giant companies make up for the lost jobs.
People see that giant companies get away with blatantly disregarding laws like the ride sharing or apartment sharing conpanies that disregard taxi laws or employment laws or rental laws or hotelling laws, or like social networks or search engines disregarding privacy laws.
In short, people are tired for reasons that have everything to do with what these companies do as traditional capitalists and nothing to do with whether they innovate or are successfull.
