This whole thing seems nonsensical. If Mythos is this super hacker by far the best thing to do is just release the dang thing. Donate as needed to cover the Curls of the world but otherwise fixing bugs is (usually) trivial once they're found. Maybe we see a bump in zero days but long term the effect is much securer code.
Playing this game where everyone is blocked by a wall with massive holes in it is absurd. A farce level affair. The black hats will grind their way through prompts while the white hats are blocked from doing a "mythos hack my app" prompt and finding their vulnerabilities.
