If they ask for data, I just fill junk. If they don't then it's just a hassle.
I'd ban them. Just give me internet, my man.
That and Bluetooth
Are they mining data? Does this promote some ambiance? There's probably 3 different answers, and you'll normally hear 1 is the reason.
It can be blocked because the wifi equipment at the cafe can see multiple MAC addresses emanating from one client, among other techniques.
Captive (noun): a person or animal whose ability to move or act freely is limited by being kept in a space; a prisoner, especially a person held by the enemy during a war.
Not an ideal term to use from a user perspective.
Thus we are left with this captive errnous detection. It feels similarly stupid as NAT in a post-IPv4 world.

I find the OS' captive portal detection to sometimes be flaky, so I often just directly visit www.neverssl.com to reliably trigger the captive portal redirect.

I used to use neverssl, but it's very different for .org and .com and I kept forgetting which was which.
This post reminded me to make a siri shortcut that just opens safari to http://captive.apple.com to trigger the captive portal.

But the URL is too complex among different vendor:
https://captivebehavior.wballiance.com/
I don't know why, even I tracked the URLs, sometimes it still fails (OS refuse connecting to the URL?).
DHCP option 114 (RFC8908) can advertise the URL to client directly, but it is not widely supported:
https://developer.apple.com/news/?id=q78sq5rv

I've interacted with these as an end user dozens of times, but in 20 years I never heard the term "captive portal". I tend to use the Apple URL to trigger them, and I never understood why the word "captive" was in that URL. Now I know!
And I still don't really know how they work (I guess I should read this article...).
