The complete silence I refer is after the incidents and leaks. They stated in their preannouncement "We reserve the right to release earlier should details of either vulnerability become public". That sounded to me that if something is leaked, they'll release earlier or clarify. Neither was done and only after the release, clarified things.

But yes, the preannounce was the right move and the leaks were unfortunate, complicating things. But if cloudflare, bunny and other actors start mitigating in their WAF, I think something has gone wrong and, either you act by releasing earlier or calm the waters saying "the exploits are wrong" as per stated in their post, they thought it was the case.
