Your Mac, iPhone or iPad may have left Apple with a serious security risk

Not a long time from private disclosure to public disclosure, but in reality not much will change. Perhaps Apple could use a more unique SSID on their networks e.g. "Apple Demo 2A422A" which would be different from store to store.

On the other hand, there are so many places with free open wifi, which could easily be used instead. I'm pretty sure most of the computers on campus have connected to either McDonalds or one of the 4 different networks available in public transport.

This really isn't a bug. Whoever was snooping could do it while you are in store instead.

There's really only two solutions here:

a) get rid of of public wifi points completely. This is compltely intractable.

b) encrypt your data sent over the internet so it doesn't matter if someone snoops it. This is the only practical answer.

This is like someone realising 'ooh if I run Wireshark in promiscuous mode I can snoop everyone on an unsecured network' but not wondering what the fix would possibly be.
