We're not talking about "other phones." We are talking about iPhones. The market is "iPhone users" not just "phone users".

The parent post said “service that's arguably a necessity to participate in public life”. I’m not sure what universe you live in, but in mine everyday life is entirely possible without iPhones.

Ah, didn't catch that line.

"iPhone users" isn't a market. Otherwise every company would be a monopoly. That is absurd.

My rant was about the rationale for government restricting ToS contracts in general. Apple is indeed not as unavoidable for participating in public life as some others. The only alternative being 'agreeing to' the Google contract of course.
