It's always interesting to me how, the more an entity has shown itself to disregard the privacy and rights of it's users/customers/citizens/etc in the past, the more people are willing to extend the benefit of the doubt that they won't continue to do so on new ventures.
This will be abused, they will overstep massively at some point, people will complain, then they'll take a cosmetic baby step backwards, and possibly provide their users with a pixelated cow icon to make up for it... then continue on their way.
Do you honestly believe facebook won't look for and find ways to encroach on privacy more than currently available free wifi does? Their entire mission is to encroach on privacy, and now they've got you connecting to their wifi hotspots at the gynecologist's office.
Just like all other "optional" features Facebook has provided in the past, they will inevitably figure out a way to hide the fact that using these hotspots checks you in, and probably spams your "friends" with a record of whatever you ate.

I'm guessing everyone has already forgotten about the "we read your posts, even if you don't post them" thing recently? http://www.latimes.com/business/technology/la-fi-tn-facebook...
