It's one thing that this happens. It's a whole other that there is a public story about this.

Having worked at a large tech company for a long time, there are very strict controls in place to ensure what is published (even under personal employee accounts), and Meta employees are some of the most tight lipped people I have come across.

If I were take a stab at reading between the lines, I would say Meta is trying their best to FUD their AI competitors... probably because they are so so far behind.
