Unless they are doing deep packet inspection or analyzing your browser through a wifi login portal, I think an iPhone's MAC randomization should be able to defeat WiFi-based tracking (barring WiFi-as-radar, those are much more difficult to evade, there is a ton of metadata you can collect from stuff like breathing, gait and heart rate etc. Cross reference with CCTV to prevent false positives.).

If you are 'logged in' into a wifi network, then MAC address randomization is turned off for that network and the iPhone gives the real MAC address of the device. It's only used in non connected scenarios such as scanning for available networks. Another bad thing is how iBeacon bluetooth is something you can't turn off specifically on an iPhone if you have bluetooth on in any capacity. And there is no per app privacy permission to turn off ibeacon processing. It's a huge privacy violation and I always wonder why it's not brought up that much.

  Oh that's terrible, I also thought the randomization is constantly on. Is this the case for Android and the desktop operating systems too? Windows, OS X, Ubuntu etc.?

    Your connection with the AP is bound to a particular MAC. You could randomize it per AP, but you can't like, randomize the MAC for every packet.

      Yes but you can randomize every time you connect to the AP.
