Server private keys? Are they somehow per-user?

I went to go download some more configs and it finally registered that every server has the same public key.  Which means it has the same private key.

Did AirVPN somehow figure out how to make a Wireguard interface with a per-user interface private key?

In Wireguard you have a pair of keys (public + private) separately for the "server" and the "client". Yes, all AirVPN servers are using the same pair of keys, AFAIK. However, your side of the connection, the "client" has its own private and public key. Every "device" in "Client Area" -> "VPN Devices" has its own pair of keys, so this way you can achieve multiple connections from one device.
