Who is "the public" here? Why should
package maintainers be hearing about this any sooner than me? I may not help maintain a popular Linux distribution, but I may very well run a service that my customers' bodily safety depends on the encryption of the SSL connection. (Hypothetical.) After disclosure, my
only option is
not to wait for a fix from my vendors and service providers, but to shut down my service (and lock out my customers) until a fix is available from them (or my own efforts) hours later. Otherwise, the bad actors who would benefit from seeing their SSL traffic would have hours to do so, and for some of us that can cost lives.
This marketing page was effective communication not just to the public, but the hundreds of thousands of technical people that needed to understand that this disclosure was different, they needed to take action, which in this world of plentiful managed hosting, is really not typical.
