No, its a reminder to turn on the built in security features in your devices like non persistent MAC address randomization.

I dont know how it is on stock android, but when you only turn on normal MAC randomization for a connection, then it will create a random MAC for that network but that random MAC will stay the same indefinitely. So you could still be tracked across a wifi mesh like a campus network. To prevent that you need to turn on both MAC randomization for the campus wifi connection and this system setting shown in the last screenshot which will randomize the MAC every time you reconnect to a network that has randomization enabled.

These aren't open wifi connections where any of this would help, you connect using your university credentials.

Thats true i guess, i didnt consider that because i use shared credentials with a bunch of people on my campus.
