From Crash.net (with apologies--read the whole thing there.)
"...Hayden falling at a crowded first corner, or suffering a mechanical failure, would have been plain bad luck and all a part of racing - but losing a world championship lead because of a team-mate's suicidal attack was plain stupidity and may cause Honda to review the wording of its 'no teams orders' rule. Certainly, it appears that Pedrosa will now have to help Hayden at Valencia..."
Julian Ryder had similiar, if not more damning, things to say.
Pedrosa can claim that he wasn't trying to pass him here, and perhaps he wasn't, but I doubt it. Regardless, there was no reason to even be that close where a small mistake could be disasterous.
