Unfortunately, the principled path is not tenable for Mozilla in this position. They were seriously damaged by their refusal to implement H.264 due to its patented nature, which they gave up recently. Mozilla has the choice of taking their lumps by swallowing this piece of crap and continuing to survive or becoming obsolete. If users can watch videos without a struggle in Chrome but can't watch in Firefox, what's the effect going to be? Firefox is already on the ropes, they can't handle another H.264 debacle.
