The fact that even a whiff of potential competition incentivized Apple to half their tax for specific cases shows that anti-trust regulation works and that it's the only thing that will ever force a gatekeeper to reconsider their anti-competitive business practices.

>It’s an admission we’re all at the mercy of Apple until daddy government steps in.

That has always been the case when market participants become too dominant e.g.

United States v. Paramount Pictures (1948)

United States v. AT&T (1984)

United States v. Microsoft (2001)

Anti-trust regulation would have dealt with Apple, Google and co by now if the lobbying weren't so out of control compared to previous times.
