Networking newbie question: why are "locked-by-password" and "secure" conflated with WiFi? Is there a technical reason for not having access points that are secure/encrypted and open? HTTPS is able to do protocol negotiation in the open, then provide a secure channel. Why is there no such thing at the WiFi link layer?! I found some discussion at https://security.stackexchange.com/questions/35867/why-isnt-open-wifi-encrypted https://security.stackexchange.com/questions/35867/why-isnt-... and https://security.stackexchange.com/questions/149422/why-isnt-a-standard-for-encrypted-but-open-wifi-developed https://security.stackexchange.com/questions/149422/why-isnt... , with wildly varying answers.
