In terms of Why free was deemed the most important consideration in media, I think there's also a bit of blame to be placed on the software industry.
Many people would never be able to afford the sometimes tens of thousands of dollars worth of software that it took for them to participate in their field. Piracy was tacitly encouraged for teens and individuals to keep corporations paying tens of thousands of dollars.
On the flip side, the Free Software movement was in full swing.
This created a generation of computer users who were raised in a world where paying for things was the mark of a foolish loser. (Who registers winrar?)
