Crowdstrike is worth whatever they can get people to pay for it. It might not provide that level of value to its clients, but it certainly sells at that price in the market.
Ayn Rand, is that you? I guess technically speaking you are correct - but that value proposition has evaporated now. They've likely lost all trust with their customers at this point.
I do hold IT departments accountable, though. A third party vendor software update should not be able to cripple your entire organization like this.
Especially since I'm assuming those organisations pay good money for those services (my org hasn't been affected and we don't use them but we're also very small so I wouldn't know).
