'They're just too big': Arizona Senate candidate Blake Masters wants to break up Big Tech and ban their business practices he believes are harmful. “I think Republicans need to reacquaint themselves with their history of antitrust enforcement, and realize huge concentrations of power in private hands can violate people’s liberties just as much as government,” Masters said in an interview with the Daily Caller News Foundation. Masters, who announced his candidacy in July, serves as chief operating officer at investment firm Thiel Capital and runs the Thiel Foundation, a philanthropic organization founded by billionaire investor and PayPal co-founder Peter Thiel.
