IMHO by now if you're still on Facebook you've made a conscious decision to let a business with an awful track-record of respecting its users' privacy basically have carte blanche over whatever you give to them.

I'm sure there are a few folks out there who don't realize this, but most people I talk to about this say they a) hate it but b) don't want to leave the platform because it lets them keep in touch with people. To them, it's worth it. Not to me.
