I'm not sure I understand what you're saying.
Getting 100% of your subscription is the same thing as getting 1% from everyone out of 100 customers, where only one person (you) listen to that artist (and exclusively).
That 99% of "your" money went to an artist you dislike doesn't matter if 1% of everyone else's money went to the artist you do like. The money doesn't know where it came from, and the artist doesn't care. Only the aggregate distribution matters.
Now I don't know how they do their reward distribution, I'm merely pointing out the flaw in your reasoning.
