They will be offering already, to stream radio to cellphones I imagine.
People use data recklessly, streaming video, radio, video calling. I know someone who sends most of their messages on WhatsApp using audio instead of typing. People complain about not getting good streaming reliability while being the source of the problem.
A bit like bad parking, people complain they never get a space but park atrociously when they have the space.
This is one of those (many) situations (pulling out of side streets, cutting in traffic queues, jumping red lights) where being a good citizen just means others get the benefit of your altruism.
At least altruism can work with data, I have a very cheap SIM-only package (4GB, £9) and never even check the amount used - I would have to be away from home with no WiFi and a laptop needed internet before I worried.
