IMO pirating media from anybody but indies is moral, correct, and good. The big companies have trade representation and lobbyists which they use to push their insane copyright agenda. Consider the Mickey Mouse act https://en.wikipedia.org/wiki/Sonny_Bono_Copyright_Term_Extension_Act which extends copyright to such an absurd term, only corporate lawyers could have devised it. Which they did. Disney is a great example, in fact, since much of their media empire relies on adaptations of public domain works which are then copyrighted basically indefinitely. If our copyright laws today were more similar to what copyright laws were back then, we could have a lot more remixes, adaptations, and takes on well known stories and media.
Anyway, by purchasing from these copyright pushing companies I am funding their agenda, which is against sensible patent law and copyright law, and against me. They also promote vile DRM schemes, as their industry pushes ever onward away from personal ownership of anything and toward rent seeking behavior. If it were up to them we would all have tivoized boxes that we not only have to pay rents for, but must also consume ads on. Literally against my own interests to give them money, ever.
It's too bad that so much of our media is produced by a shrinking number of companies, because pirating their shit isn't even worthwhile. Most of their garbage is unwatchable slop.
As for any other form of piracy, I consider intellectual property to be mostly bullshit. But I can appreciate the time that goes into creating a work one wishes to sell and having some domain over that for a period of time after initial publication. But like many other things about our world, it's the stupidest version we have to live with.
P.S. and that's just one aspect of copyright law. Imagine trying to copyright the fundamental advances of human knowledge and science. God bless Sci-Hub!
