So let's get this straight:
The MPEG-4 "open" "standard" (creative uses of both words) is so encumbered with patents that to use it, you have to pay 25¢ per decoder, and 25¢ per encoder, to make use of it.
Microsoft undercuts them by charging 10¢ per decoder, 20¢ per encoder, or 25¢ for both.
The MPEG-4 consortium cry foul because "the interest of consumers is best served by open standards."
This is another one of those, "who is more evil, Union Carbide or Phillip Morris" situations, isn't it?
