I don't know the legal specifics, but in some countries I've noticed all public WiFi requires PII. It's become more and more common. I mean you can still find open ones at like small hipster coffee shops, but it's to the point where it's quite rare/inconvenient

You usually know if a country's wifi will be a pain in the ass by going to a Starbucks and seeing their wifi portal. Some places you need nothing and some they want a birth-certificate/blood-sample

Looking at you Germany

I wouldn't bother thinking about this in Europe already due to the free cross-border roaming. But for instance in Southeast Asia, it was pretty common that all the bars and whatnot had a WiFi that was granted to you with a mere password, although guesthouses' WiFi was to my memory linked to your room registration. And there were still a lot of WEPs and whatnot, and the cyber crime is booming there anyways so the requirement to disclose your details sounds like a security theater anyways.
