The rollout of Mythos was clearly manufactured to stoke the fears of companies that didn’t have access to it. They also bragged (for Fable) about how they "ran an external bug bounty that produced no universal jailbreaks in over 1,000 hours of testing" only for it be circumvented almost immediately.
So them standing on the high horse and saying it is _so powerful, yet so safe_ only to have that blow up in their face just made it that much easier to make an excuse to do this. Again, not disagreeing, but they made themselves the tall poppy here.
