People aren't really ripping Star Wars to protest against long copyright periods. They're ripping Age of Ultron so they can watch it for free.
I am not so sure of that claim. Sure, some people are downloading it so they can watch it for free...
I am considering downloading it myself currently. I could watch a censored version in the theater. I could wait 6 months or however long for a dvd (I do not do bluray) to come out.
I downloaded the first Avengers movie for the same reason. I eventually bought the dvd and ripped that and deleted the version I had downloaded... but only because the version I had downloaded was inferior to rip I had made.
I also downloaded Star Wars. The REAL version where Han shot first and there was no CGI Jabba. I think you can guess why.
People aren't downloading cracked versions of Donkey Kong. They're downloading cracked versions of the latest Assassin's Creed.
Actually, I did download Donkey Kong last month. I wanted to try out MAME again and lost all of my old ROMs. Assassins Creed is crap, but to stay true to your argument, I did download Skyrim and Civilization 5.
DRM pisses me off and I never buy anything prepackaged anymore. I found Skyrim and Civ 5 on Steam and decided the DRM that Steam provides is a worthwhile trade for the convenience of being able to download it anywhere and anytime and play it on any computer. I plain bought GTA V through Steam without even downloading a cracked copy first... but only because the GTA series always has an interesting world to discover even if gameplay can be flat at times.
In short, downloading games is a try before you buy proposition for many people. If you like a game and never buy it, you will not continue to see good games being made.
These things would have been illegal under even the earliest and shortest periods of copyright protection. These are titles that took hundreds of people and millions of dollars of investment to make, and the law effectively requiring people to contribute in return for their copy does promote the useful arts by making such projects financially viable.
Fuck them. They lobbied for and got copyright extensions that are so beyond reasonable that those laws actually violate the entire purpose of copyright. I do not care what is right in relationship to copyright anymore. It is pure fucking war. I try to play fair but get fucked every god damned time. Fuck them. They already said fuck me.
