There's even comments in this HN thread that point you on how to do it on Android if you're so inclined.
At some point users are allowed to complain about shady behaviour done by huge corporations with resources they use to try to thrust their way into everyones lives.
I sometimes will load a website that uses React when really it's just a static content site. It just gets tiring, and doesn't add to the conversation, when every discussion about an article that could be HTML devolves into that. I get that other people feel that way, and in many ways I share their values... But it becomes its own sideshow and hijacks the otherwise interesting conversations, without adding anything new.
I'd give more credence to "the market is making an informed choice" hypothesis if consumers were, in fact, informed.
Wrong. At least for EU citizens.
If Spotify are collecting data in this way (and not only using the SDK for Facebook Login), they are in violation of the GDPR. There must be clear unambiguous consent to collect the data in the form of an affirmative action of the user and it must be possible to use the app without giving consent, because the Facebook data collection is not essential for the app to operate.
If they do share data with Facebook, Spotify should be scared, since they are definitely large enough to be on the radar of the EU or national bodies.
Moreover, outside the EU it would be dumb for Spotify to say "just don't install the app if you don't agree". The 10 Euro per month that premium users pay is worth more than some Facebook tracking.

It's kinda worse. They "only" open the gate wide and any of your data they can see is there for Facebook to take. It can feast on any data it can grab with the same permissions the main app has. Like a fucking virus from MS-DOS times infecting binaries, but this time developers are doing it quite voluntarily.
