The FCC in USA is about to vote to get rid of the net neutrality, letting ISP's censor and throttle websites, and charge extra fees. This would allow ISP's to throttle this site, when they don't like the idea of every student learning about robotics, technologies and generally how to think.

The FCC will end net neutrality on Dec 14th if we don't convince Congress to stop them. Join the Protest and Contact Congress to save net neutrality.

If you are not from USA you should also be alarmed. Similar policies are already in the process of implementation in the other 59 countries in which FLLCasts.com is used. We should fight for our Internet freedom regardless of where we are from.
