Tech outage brings massive disruption worldwide including major air carriers to full stop

so in laymans terms, to fix you need key. the key is stored on a server you cannot access because of the original issue and have no way of getting into that server?
Yes, although for someone to get into that situation, they've probably already made a big mistake themselves (because, e.g. if a recovery key might be necessary to fix that server first, that key definitely shouldn't be stored on that server). But there can be other reasons why fixing that server could be difficult.

And then even with the keys, it's the scale of the problem. Companies with potentially hundreds, or thousands, of potentially remote workers, with bitlocked laptops. I would not want the job of remotely talking hundreds of people through booting a bitlocker-protected system into recovery mode and deleting a system file.
