The law of unintended consequences, and the unintended consequences of law.
Lots of people claiming Microsoft is making excuses, but no one has explained how what they said is incorrect: EU required Microsoft to give kernel level access to third parties. Third party software with kernel access release a bad update that crashed their systems.
Pray tell, how could Microsoft give full kernel access and prevent a third party from creating a sh*t storm? How could Microsoft have fulfilled the EU mandate and not also give companies like CrowdStrike enough rope to hang themselves?
