In any case your own chief of security coming out and saying your security is crap would be devastating for any company. But when it's a person with credentials list like Mudge's - one can be quite sure he's not just doing it because some disagreement about salary and vacation days, and it would be impossible to dismiss this as "disgruntled employee issue". Twitter would probably try anyway, but it won't work. Twitter is going to be in a lot of hot water now, and I can't imagine Musk isn't going to milk this to the last drop.
