Having the same WPA2-PSK authentication secret does not allow spying over WiFi, unless you are willing to actively spoof the network.

Yes it does. If you capture the authentication handshake, it's as straightforward as putting the passphrase into Wireshark.

I could have sworn there was a DH key negotiation? And I worked in WiFi for a decade, a decade ago... Sorry, obviously I have not had enough coffee yet today.
Looks like this was only added in WPA3!

I think you can also do it with WPA2-Enterprise, so a common trick is to set up enough infrastructure to let your users use EAP-TLS or something, and IIRC EAP sets up a per-client session key in the handshake. The public LinkNYC wifi network, for instance, has both an open network and an EAP-TTLS one that you can download a provisioning profile for.
