Practicing What You Preach

There has been a large amount of smart commentary on this today, but I’d like to beg one question:

If Cory Doctorow is so opposed to closed systems owned by large corporations, why does Boing Boing use Adobe Flash for its advertising and video?

He’ll criticize others for their use of proprietary tech meanwhile profiting from another? As an editor and public face of Boing Boing, this seems a tad hypocritical.
