In my opinion it is perfectly fine for society to order a company to hypothetically limit you on this minor thing (and let's be frank: this is super minor), because opening up iOS would benefit companies, countries, economies and other users of phones.

It's legitimately easier to just buy a UMPC with an LTE card and use VOIP than do that. That's how bad the situation is at this point.

I say this as someone who gets paid to work on open source and used PostMarketOS on my primary cell phone for years. Even technical people really only have two options right now.
