A 2020 report by the Committee on the Judiciary of the House of Representatives found that the Big Four tech firms - Amazon, Apple, Facebook, and Google - engage in systematic anticompetitive practices.

“For example, in 2020, the Committee on the Judiciary of the House of Representatives wound up a lengthy investigation of four big “tech” firms— Amazon, Apple, Facebook, and Google—, and concluded that all of these firms engaged in systematic anticompetitive practices. Thus, the Committee’s Final Report notes that “[b]y controlling the infrastructure of the digital age, they have surveilled other businesses to identify potential rivals, and have ultimately bought out, copied, or cut off their competitive threats.” In other words, efforts to protect free markets from anticompetitive behavior remain essential.”
