The security issue aside, seeing more companies push announcements like these on X as the only official source is a trend I'm not sure I like.
I can understand the rationale, this feels lighter and not something that belongs on status.github.com or the blog. Maybe what's actually missing is an official channel for ephemeral stuff on a domain they own, somewhere between a status page and a tweet? Just sharing an observation.
My understanding is that when it's something that requires user action they'd directly send comms to customers.
