True that copyright always existed to protect publishers and not creators. But in pre-digital times there were considerable barriers to publishing and distributing creative works at scale so while publishers in all media have often abused creators they were a necessary evil if you wanted to make a living.
The worst trick greedy capitalists have pulled recently it to bypass copyright and steal the entire digital record of human creative labor to incorporate into proprietary models and services for their own enrichment. I have no idea how society and our political representation has slept through that. The second worse is insanely destroying their own industry by fucking over both consumers and creatives with increasingly unsustainable greedy and dumb bullshit.
Access to education and other equitable causes really should be fair use. If everyone pirated, and the way things are going it will be the only sane way to get content, then new content is going to dry up unless people are happy with AI slop. We will still see indie self-published works but necessarily the creators won't have access to the same resources we saw when they were part of an exploitative but productive industry. That sucks. A lot of people are happy to pay for convenient and affordable access to content under reasonable conditions and piracy is something they only resort to when that is denied.
I - for one - welcome the solarpunk future where we'd meet up with friends to watch indie self-published movies because that exploitative but productive industry didn't make it for lack of a viable business model.
Piracy has always been a distribution issue. There are definitely greedy lazy people who will always want more for less, but the organized effort required for piracy only happens when fair access is impossible.
I think the problem is allowing corporations to own the copyright. We should make it so that only the original creator of something can copyright it for ten years.
