The problem (with this post in HN) is that it _isn't_ actually automatic. Your device being receptive to automatically-shared networks is default-on/opt-out. Your device automatically _sharing_ a network is default-off/opt-in, as well as (I think) being on a per-network basis.

This is correct. None of this is automatic. It's all opt-in.

I don't believe Wi-Fi Sense is on at all by default (I am pretty sure I had to turn it on), and it explicitly shares only Wi-Fi networks you select, not all of them. You have to go in to your saved Wi-Fi networks and share each one individually. You also have to individually check each list of contacts (Outlook, Skype, Facebook, etc.)

It is absolutely not sharing all your networks automatically with all your Facebook friends.

Here are screenshots (note I'm 99% sure I turned on Wi-Fi Sense):

I suppose it's ironic the FUD is directed against Microsoft now.
