I hate to keep criticizing mega-ISP Comcast -- life, after all, is unfair enough for our major corporations. But it's hard to let this one by without comment:

FCC Chairman Kevin Martin on Tuesday told Congress it appears that Comcast used technology that completely blocks certain traffic, like peer-to-peer file sharing.

Martin's testimony contradicted claims by Comcast. The head of the Federal Communications Commission  told the U.S. Senate Committee on Commerce, Science and Transportation that cable subscribers do not have the freedom to do what they want on the Internet.

Well, not yet, anyway. Still, there's plenty of time for a White House executive order.

According to this Reuters article published on internetnews.com, the FCC chair testified that "Comcast had used a 'blunt' technique to impose broad restrictions on peer-to-peer file sharing."...

"Contrary to some claims, it does not appear that this technique was used only to occasionally delay traffic at particular nodes suffering from network congestion at that time," Martin said in prepared remarks.

The FCC is looking into complaints from consumer groups that cable operator Comcast has unreasonably blocked or hindered some file-sharing services, such as BitTorrent, that distribute TV shows and movies.

You know those consumer groups, always jumping the gun. All kidding aside, here's a perfectly reasonable  explanation for why, in the words of Martin, "some users were not able to upload anything they wanted and were unable to fully use certain file-sharing software.":

Comcast, which has more than 13 million broadband subscribers, has denied impairing some applications and has said it merely managed the system to deal with network congestion for the good of all users.

For the good of all users. Comcast, maybe I had you all wrong.
