@ardgedee that makes perfect sense, and it was also suggested by @hilljam a few minutes ago.
I'm torn because I see the fallacy of my position, however there will be other Bandcamp Fridays and I'd rather put a temporary halt to purchases on the site because it sends a stronger signal. Emailing ethan@bandcamp.com also could drive some points home, maybe.
I'll think about it. Please consider that I'm an artist too, on Bandcamp, so I double-get it. Thank you both for the counterpoint.
