Its not that they react to being ripped off, its that they react more like Los Zetas than law abiding shop-keepers when they do.
RIAA/MPAA mission is simple:
They want to own all of the content, control the ways to distribute that content, that content to be used only as they say, forever.
Because Disney is sure as shit related to the first.
The reasons they may be hated for that don't bear much relationship with copyright infringement which focuses almost exclusively on newly released things that would be copyright regardless of Disney's lobbying.
You are the one attempting to insinuate that only people who use The Pirate Bay object to their perversion of copyright laws and discussion. Multiple alternative reasons to be angry with them have now been presented to you, but you just claim they are unrelated because you assert that the real reason is that they are just interested in pirating recent things. In discarding these alternative reasons because they they don't mesh with your already unsupported assertion, you are begging the question.
People are in fact upset with the MPAA/RIAA for their abuse of terminology and all that it facilitates: the corruption of copyright laws, weaponized lawsuits, and the shackling of (frankly ancient) culture.
Pretend that people are only upset with their abuse of terminology because they want to pirate things all you want, but you are dead wrong.
I think that people pirate primarily opportunistically. Some of these people try to justify their piracy by saying they hate the MPAA/RIAA and pirate for ideological reasons, other pirates do not.
People, sometimes people who pirate, sometimes not, hate the MPAA/RIAA for a wide variety of reasons that have been beaten to death in this thread.
I don't dispute people are upset with the MPAA/RIAA, just that it has very little to do with Disney or material that shoulda/coulda/woulda been public domain at various times in the last century.
Centuries before Disney was created the copyright length was still decades longer than the age of material people primarily pirate.
You cannot strike out the possibility of non-pirating critics with evidence of what pirates prefer to pirate, since all critics just being pirates is your unsupported assertion.
1. Critics are pirates.
2. Pirates pirate new material. Pirates are not concerned
with old material.
3. Critics are not concerned with old material.
Rabid public adoption of music and video piracy is most certainly a function of the public's perceptions re: price/value and anger at blatant collusion on the part of record labels to inflate prices.
