I kindof assume a decision meeting just finished, and the CEO took to Twitter the same time the PR department started drafting emails.

I expect the email contains much more specific instructions and an actual process to follow. These things take time to write, even at SEV1 priority.

The CEO is biasing towards speed of notification, so they tweet some quick details out ASAP while the PR team gets moving.

That’s just my perspective tho. I am assuming many things

Not it’s not. It’s good communication

Better to hear directly from the CEO in a distributed fashion. I see that as taking ownership (compare to LastPass)
