It'd be better if it had fm transmiter, so you van turn car radio or normal old radio into a useful wireless speaker

All my Android phones had FM radio, what are you talking about?

Digital FM? Analog is a piece of crap

But why?

Are people missing some ads that they could otherwise be getting with an FM radio on their phone?

Radio has enshittified it's way to being turned off whenever I get in a vehicle that has it turned on, so I'd miss any emergency broadcasts anyway. Can't imagine paying extra to have it on a phone.
