If you find something solid let me know. I’ll correct the post if needed. The branch started by @aaribaud seems to have the most insight, implying that the EU is distrusting WPA and using an app to do TLS.
(update) I think you are right. I just heard from someone saying it’s a regular hotspot with captive portal. Still not good but not as bad as an app mandate (like we see with eduroam).
