They don't give a lot of details but they give enough for it to be pretty hard to say the claim is false but unfraudulent.

Some researchers got a breakthrough and decided to share right then rather than the months later it would take for a viable product. It happens, researchers are humans after all and i'm generally glad to take a peek at the actual frontier rather than what's behind by many months.

You can and it's fair to ignore such claims until that part but i think anything more than that is fairly uncharitable for the situation.
