"If your speech is free then you shouldn't be able to charge money for people to listen to it!"

It's a pretty simple argument, and it's been around since even before Windows. Even back then Bill Gates had to explain to these people that he literally would never be able to share Microsoft's works if he wasn't charging people for it.

I would not be upset at all if Linus Torvolds started charging me to be able to use Linux. I care most about the right to privacy that every human is born with, not the privelege of software that depends on the active efforts of others.
