My freedom to create another avenue for people to freely speak their minds will always be something never fully controllable by corporations. Even pretending for a moment the corporations get down to the media level and start controlling the wires and trying to prevent people from sending whatever data they want to and from servers, we are in a free market so smaller time competitors that fully allow freedoms to post/print whatever will rise to the top.

It's the beauty of a free market. If AT&T decided they were no longer going to allow X-type of content to travel their wires, then a bunch of us get together, and create Freenet, an ISP that simply provides a "dumb pipe" to send data over we would suddenly receive all the business.

YouTube is not the end-all, be-all of video sites on the Internet, and any censored content is easily obtainable at other places where they will not censor. As long as the free market remains open (as it should), the people will continue to be truly free as entrepreneurs will simply start up other means for people to freely express themselves.
