Amazon and AWS auth was finally split late last year I think?

If there was a real and urgent issue, Amazon I expect would have had to make a statement by now or risk regulatory action. (E.g. the GDPR requires public disclosure of data breaches within 72 hours). They haven't done so.
Right now this is indistinguishable from some random dude complaining about a minor bug to Amazon, feeling Amazon is dismissing him, and hyping up the issue to try to put pressure on them.
