I don't want to use my phone for basic features like the offline mode, I'm not always connected to the internet on my laptop, that's it.
I don't care about Apple music, and almost every streaming platform provides some kind of SDK. It doesn't change the fact that I don't have a Linux client, and probably never will (or at least feature-complete) because they partly use Dolby Atmos, which is a closed-source licensed format.
And no, even on paper, tidal's not the better option to support artists. Buy tracks on Bandcamp, buy merch and vinyl directly from artists...
