That isn't the same at all: Mozilla and Google are producing actual products that embody competing standards, and both Google and Mozilla have a lot of power/control over "what comes next". Given both Google and Mozilla's track records, I'd say that Mozilla's concern is warranted. Your analogy might work better if Mozilla was a non-practicing committee that brought a competing standard with no implementation out much later.
