Hyundai and Kia added official GrapheneOS support to their apps months before Volkswagen banned GrapheneOS:

Pressure from Volkswagen customers on them can achieve the same thing. There's no legitimate reason to ban GrapheneOS so they'll undo it with pressure.

Leave a 1 star review for Volkswagen's apps on the Play Store asking them to stop banning GrapheneOS. Explain it's a far more secure operating system and fully possible for them to verify the hardware, OS and their app on it if they insist on doing it. It's far more secure than anything they allow.
Google has misled companies about what the Play Integrity API provides. It doesn't genuinely enforce having a secure device or legitimate app, it only pretends to. It leaves huge security holes open. It enforces Google's business interests and bans having a reasonably secure device with GrapheneOS.

@GrapheneOS

I don't use #spotify much and I'm even thinking about deleting my account soon

But lately, I've noticed this little "Play Integrity API usage" window whenever I use Spotify on GrapheneOS

Is this something to be worried about?

@frank @GrapheneOS it'w why i bought my music and now use syncthing to sync them.

now they cannot block my music anymore

@skyblitz @GrapheneOS

Spotify isn't blocked or anything, but I just don't exactly know what it is.

This windows shows up the moment I hit play.

Lately, I've been thinking about deleting Spotify and use NextCloud music instead.

@frank @GrapheneOS if i where to guess, they implemented it but "yet" not enforce it to catch bug, and later they will enforce it and will stop after an update.

so if you want to maintain it, it's now to report the issue.

but i decided another road, exported the name of all my music, and bough all of them.

@frank It's nothing you need to worry about as long as the app is satisfied with the result and continues to work. But from what I see at friends' Spotify is enshittifying at record pace, so even without considering the company's investment in AI weapons or their treatment of artists it's a good idea to ditch it.
@skyblitz @GrapheneOS

@menos @frank @GrapheneOS at the end of the day i buy what i could from bandcamp so artist win more on my purchase that anything any of my subscription would have given them.

for older artist with pocket full of money i hunted physical disk that i have ripped.

and the rest from quobuz.

if and only if i didn't find them on purchase legally, i had been a little more innovative from the where i found them.

Edit: only 1 music is in this last case, that is a little more exotic.
