The part saying he robbed streams from legitimate artists and fans is quite stupid but expected in a case like this.

It says he robbed royalty payments which is true because of the way most of these services distribute royalties. All listens go into a global pool and count the same amount. So if you listen 20 hours a day, you control not only the royalty payments from your subscription but the royalty payments from several other people's subscriptions.

If there was a sane payment system for spotify it would be literally impossible for that to be the case.
