That's the thing about copyrighted content - even if you sell it, you don't "sell" it. I paid to have a private copy of "The Two Towers", but I sure as heck don't own it in any sense of the word.
Respecfully, I disagree. You are believing what the MPAA and the RIAA has been saying, not what copyright law says. Don't believe them.
Someone sells a copy, they
sell a
copy. Period. Copyright law only covers the rights to copy something. Media and software companies are trying to get people to believe that you don't own what you buy. Don't believe them. Don't accept their philosophy, which has nothing to do with justice and morality, but solely is a doctrine to conveniently make them more money and force you to buy things more than once.
I own the copies of Win98 and Office 97 that I paid for, no matter what MS says. I own all my CD's no matter what the RIAA and SONY are trying to tell us. I don't own the rights to copy and distribute (beyond what is covered in fair use doctrine). If companies start to whine that content is "their intellectual property" beyond what conventional copyright law covers, they should just keep their precious "intellectual property" to themselves.
