Is using streaming services worthy of an audiophile?


I read that a lot of people on this forum use Tidal etc. Is this ok from audiophile perspective? I mean, do people who use such services actually know what quality is streamed? Don’t you lose all control over your music when you surrender to streaming services?

Could you be a bit more specific, please. 

Specifically, how do you know that the claimed file quality is actually streamed? What prevents streaming services from downgrading their signals?
