Cuban owns movie theatres and also the rights to several movies and TV shows and simply believes that P2P technology should have the right to thrive. "It will be a sad day when American corporations start to hold their US digital innovations and inventions overseas to protect them from the RIAA, moving important jobs overseas with them," Cuban wrote. "That’s what happens if the RIAA is able to convince the Supreme Court of the USA that rather than the truth, which is, Software doesn’t steal content, people steal content, they convince them that if it can impact the music business, it should be outlawed because somehow it will."
Not many details were given on what financing he will offer or how much but we do know that he has pledged to fund the EFF's (Electronic Frontier Foundation) defence of Grokster. Whatever way you look at it he is brave to stand up against his peers and side with P2P. "This is the big content companies, against me. Mark Cuban and my little content company."
