Google or any open source map product. And actually, if we use the SCOTUS approved DOJ v MSFT consent decree as precedent, any app that can't use this private API component would be an impacted party.

I'm an antitrust nerd - 20+ years since I made my first PACER account as a teenager to get documents from interesting cases..

95% of what people call "anticompetitive" or "monopolistic" has no legal bearing. People don't know the legal definition of those words and bandy them about based on vibes.

This however, is a very very clear case of violations of precedent. If we look at Microsoft's final judgement https://www.justice.gov/atr/case-document/final-judgment-133 see F(1)(a), H(2)(b), while these stipulations haven't been applied to Apple, if I were in a market dominant position, I'd be super careful about capricious restrictions like the example undocumented API, and behavior that mimics patterns of activity that were seen as actionably sanctionable to similar market dominant forces
