Have you used Nord VPN? These aren't questions users would have. I could be wrong, but I'm confident that a plumber that has used Nord would know what a datacenter is, just from using the app. My tech illiterate Dad (70s) sure does.
VPNs are advertised a lot on all kinds of YouTube channels. It is reasonable to believe that they have a bunch of customers who know almost nothing about VPNs or the Internet in general.
Those are also the customers that won't even know that this hack ever happened, or won't care, because "everyone gets hacked anyways".
You said you wanted them to give a clear explanation, which I believe they did, but you don't. Let's just leave it at that.
These companies are giving all their customers the idea that they have reasonably good anonymity with a public VPN service, which is arguably false depending on how they use it. I feel like that's where you should be targeting this concern. Not an expired key leak.
