> Bandcamp, which Epic acquired in March, has used its own billing system on Android since 2015, and was able to do so because of rules exempting digital music from having to use Google’s billing system, according to a blog post from Bandcamp co-founder and CEO Ethan Diamond. “However, Google is now modifying its rules to require Bandcamp (and other apps like it) to exclusively use Google Play Billing for payments for digital goods and services, and pay a revenue share to Google,” Diamond says. Didn't Google just said they allow Spotify users to choose between Google vs Spotify payment system? Why are they now requiring Bandcamp to "exclusively use Google Play Billing"?
