I agree. Whether or not it is what they are intending (I lean towards they are), IMO it has been strongly inferred in all the messaging from frontier models that it's impossible to secure software, which is just not true. In reality, it's now possible to find and fix problems faster. If attackers/adversaries can just point LLMs at software and dump zero days as we are warned/told repeatedly by every LLM vendor, then literally anyone can do it now. If that is true, then if you want to be marked safe from AI enabled attackers, test your own software with it.

I guess the doomsday stuff sells more...

This highlights a problem with the Anthropic-Mythos-restriction style "we regulate the best models so attackers don't have them": It also ensures that only the big-guy partners of the program (Glasswing in their case) have the capability to secure themselves at the frontier model level.
