* not every artist has a donation link. * I don't get the album for free otherwise

So I think it's totally ok for the service to give 10% to bandcamp (or whatever camp it will be in the future).

But I would be really happy when something like Faircamp takes off, and is easy for artists to use (or labels etc.), so they would be having more control, while providing a clean interface (unlike e.g. Qobuz)
