When will they learn? These corporations need to adapt to the market. The market dictates that barriers will always be circumvented.
Netflix is a shining example. I can get movies fo' free through torrent. However, this can be a tedious process for certain movies, formats, etc. That's where Netflix comes in. I pay for Netflix because it offers what torrent doesn't; convenience. I can instantly stream HD content on demand, and through a slick interface. $8 a month? excellent.
In Europe they have Spotify, a free, ad-supported music service that is legal, profitable, and convenient!
The market has shown time and time again that it will not bend to fit the needs of the corporations. Rather, the market has shown that charging exorbitant prices and restricting access leads to more piracy, not less.
