The Federal Communications Commission (FCC) today voted to stop Comcast from blocking legal file-sharing activities on its network as a violation of the FCC's net neutrality principles.

The fact that the FCC felt they had sufficient grounds to hold Comcast accountable shows how egregious the violation was, as the FCC's principles are weak and it has given itself limited enforcement capacity.

It is unclear at this time if Comcast will be fined, but at the very least they must stop blocking peer-to-peer traffic and disclose the methods it uses for "network management."
