Also from Jamie Zawinski yesterday: Mozilla's Original Sin

Some will tell you that Mozilla's worst decision was to accept funding from Google, and that may have been the first domino, but I hold that implementing DRM is what doomed them, as it led to their culture of capitulation. It demonstrated that their decisions were the decisions of a company shipping products, not those of a non-profit devoted to preserving the open web.

Those are different things and are very much in conflict. They picked one. They picked the wrong one.
