I don't even know why we're spending time blaming anyone here. The only reason any of these vulnerabilities matter is because bad people do bad things with them. The night of the disclosure, I saw reports like this one and many others, and it was more than enough for what I thought any reasonable person would deem to meet the bar for early release. It turns out reasonable people can disagree on almost anything.
I'd rather we all collectively spend this time talking about how we go fix all the rest of the vulnerabilities we (and everyone else) are finding as quickly as possible and get the patches and mitigations deployed to everyone that needs them as quickly as possible over the coming months.
(I'm the guy that decided to release these early)
