I make a living off of media creation and have for over twenty years, across multiple mediums and in different capacities. Some of the stuff I've worked on has been DRMd and some has not.
The financial benefit coming my way has not been dependent on DRM at any point to any extent I can discern. You want to impact "the right to financially benefit from their creations"? Fix the fact that companies can just hire a creator to work for hire and own all their output in perpetuity with no requirement for additional compensation and indeed no IP rights staying with the people doing the actual work.
If you're gonna high horse me with the morality of financially compensating creators you better be talking about the actual creators, not the corporations keeping the bulk of the revenue.
Again, you're looking at it wrong. Or weird, at least. It's like asking why I'd be mad that the brand of cookies a member of my family eats gets a price hike if I don't like them myself. They're still in my shopping cart every week.
I don't have a concept of a "primary sub holder". It's stuff a group of people gets for the group, and who is paying for which specific parts of the fixed expenses is lost to the mists of time.
I get that US and anglo cultures in general are less collectivist, but this seems more extreme than that. Surely the concept of a close-knit group of people sharing costs without much precise bookkeeping is not completely alien to you. Do you split grocery shopping with the rest of your household? I mean, I did that when I was sharing an apartment during university, so maybe it's an age thing?
