Well nothing, this is news to everyone as of today.
And the Q&A discussed audience questions like "What can I do to be a better employee?" if you need an idea of the type of questions being asked there.
Jassy's answer to that question contained this tidbit about "how to build a strong team? ... go into the office ..." At that point I was certain the RTO message was coming and it was just a matter of time. Turns out that time was today.
