Do your part, Speak out!
If you believe in net neutrality, then please speak out. There are many ways, from blogging about it, posting MySpace bulletins or just telling your friends. Which ever path you choose is up to you, but please do. If you don't fight for your freedom of speech now, you may never get the chance again.
The only reason Virgin has any power is because of their user base. The less users they have, the less money they will make. This will show a huge sign that internet users will not put up for being stabbed in the back like this. It will send a message to Virgin as well as every major ISP that they cannot limit internet usage or else the consequences will be dire.
Help put an end to Virgin by never doing business with them again as long as they promote corporate control. Do not use their travel services, do not buy from any of their stores, cut any internet service contracts you have with them. Tell your friends to do the same. Get your self a website. (Resources for doing so here.) Do whatever you can. Remember, the more activism we have, the bigger the message we send Virgin Media and the safer the World Wide Web will become.
