I'm not a Google apologist and I don't appreciate your tone. I'm attempting to orient myself so that I can think about what is right and wrong with respect to responsible disclosure in a clear and coherent fashion.
As stated elsewhere, the original bug was reported in April and not publicly disclosed until July. The issue here is that the patch did not sufficiently remove the flaw. This gets to the crux of the debate on what is "responsible" disclosure. One would assume that the patch would be studied by legitimately malicious attackers and presumably they would independently realize the flaw still existed and continue abusing it. By stating that the flaw is still present the public at large can make educated decisions about their handling of MMS messages instead of assuming everything is fixed when in fact it is not. The flip side is now that less capable malicious attackers will also be made aware. And so the endless argument continues.
