This decision means there are no protections for consumers’. Companies selling Internet access are free to play favorites with content on their networks, to throttle certain applications or simply to block others.

This does not only prevent illegal downloading as the ISP would like you to believe.  In the US, comcast deliberately slows down Google searches in favour of Bing, because Microsoft threw a bunch of money at them.

Potentially your ISP could block whatever they like including your use of tumblr or twitter, and make you pay for their versions. They could slow down the speed of your facebook access and then charge you for full access.  These ideas are far fetched and very unlikely, however the possibility does exist.

What do you think of the courts decision against the FCC?
