> Disclosing an 0Day root authentication bypass vulnerability on Twitter isn't cool, even if it is local: think of the impact to shared iMacs on university campuses. It gets the word out quickly. Releasing proprietary software with such a hilariously insecure authentication system isn't cool. This isn't free software, produced by people & corporations out of the goodness of their hearts; rather, it's something for which people pay a good deal of money and which they have a right to expect is at least somewhat secure. Getting the word out, fast that a) there's a huge insecurity and b) it's in Apple software provides benefits to those running macOS (so they can fix their systems) and to those considering running macOS (so they can evaluate whether an alternative is more appropriate).
