At least that’s what would happen if an experienced hacker did the same thing.
If you ignore the context of a massive company doing an oopsie daisy and a malicious hacker intentionally trying to cause the same disruption, that makes sense. Fortunately, most people are aware of the difference.
They will most likely either be sued or have financial repercussions, although there realy isn't a replqcement waiting in the wings if they went down. Plus they have had a pretty solid reputation for years, so an occasional oopsie is going to happen and as long as it doesn't happen repeatedly it is likely to be forgotten about in 6 months.
Heck, I wasn't even impacted because my work laptop was off and it was already sorted out before I turned it on that day.
