Make no mistake, that is one of the top 5 arguments that "Leave the trillion dollar company alone" types love throwing in every discussion regarding this topic. It's not an accidental or innocent kind of argument, it will pop up under pretty much every article that discusses Apple and Anti-Trust. It's an underhanded way of defending Apple's anti-competitive business practices akin to "let Apple be anti-competitive or [insert doomsday scenario here]". Instead of advocating for application of proper anti-trust measures in order to restore a healthy and competitive market, they want to maintain the status quo where the Gatekeepers can do as they please.
