Lol the gizmodo article about the preview of mythos has this incredible openly line:
If Anthropic is kind of like a kid at a Halloween party with a bowl full of spaghetti, telling its blindfolded friends the spaghetti is brains, European cyber agency leaders are like kids who are mad that they still haven’t gotten to stick their fingers in the brain bowl
Anthropic in particular seems to use "we're scared of what we can do" as their marketing strategy. So maybe this unauthorized use is real, or maybe it's just more PR.
