Eduardo, this is a fantastic article (not that I have become used to expect anything less from you) and an excellent summary.
The only thing that I would like to add is my interpretation of why W3C failed. Giovanni Falcone,a famous italian magistrate killed by sicilian mafia, used to say "follow the money...".
Alas, this applies also to other industries. Not only the mafia. As long as there are commercial interests to be defended (and novarra was the clearest example of this, IMO), everyone was there inside W3C with their high-falautin justifications of why it was ok to piss in the water everyone was drinking. Once the transcoder wave was gone, nobody could care less and the CT initiative died (in all honesty, it had taken a nasty turn already because of novarra and others, so I am not so sure that abandoning CTs was such a bad idea).
I do not understand why nobody high up enough in W3C did not take a decision to do something in the name of the mobile ecosystem and exploited the chance to give W3C a central role as the sheriff of the mobile ecosystem,...but I digress.
