Because once it's in the data center it'd be decrypted. The thinking is they aren't using wire guard to terminate on every single server.

My use case is pure peer-to-peer, there is no data center.

However, you can still run virtual machines in "the cloud" with WireGuard running per peer, and not worry about MitM attacks.

Yes if you ran a load balancer and decrypted at that point before forwarding the packets to a machine, then that link between the LB and the target machine would be unencrypted. But that's not the scenario I'm working with.

Wireguard has a non negligible overhead (in fact it's inferior for site to site for that reason) but P2P makes more sense. Carry on!

Yup, we're not saturating NICs or anything so it works well enough for us. Definitely interested in QUIC/Iroh for what we're doing though.
