Just for uploading some songs and footage that he deleted in the end when they sent him a cease and desist?
Here's what happened, more or less.
So, the songs leaked and Marty decided to upload them since they were already out and there's no official way to hear his music.
Bungie sends him a cease and desist, tells him they're going to release the songs themselves, and Marty does the right thing and decides to take them down.
Then, Bungie releases the songs as bonus content available exclusively with the Destiny vinyl soundtrack, which was available only in limited quantities.
Marty said fuck it and reuploaded the songs since obviously there's still no way to listen to them officially except on a fucking record.
I don't really care about the fact that bungie was legally in the right or that Marty knew this would end up happening. They fucked him coming and going and this is obviously about spite, not money.
