Some of the folks who don't like the AI and especially the Calling features and drop in, just like their privacy and see it as encroachment on that aspect of their otherwise private life. It's really kind of funny how things really work though. Nowadays you can make a phone call on your cell phone and something that you discuss will end up as and Advertisement on Facebooks sidebar, even though you have never searched for that item or have no need whatsoever. With this post about nothing I will offer up that I watched a demonstration about this, where a guy with no cats, talked outside of social media about needing some cat food just to see what would happen, and within a couple of hours he pulled up his facebook page and there it was, an ad for Cat Food... Just a few conversations in his life outside Facebook and with no other searches for such things... I think some of the concern may actually be justified, however I don't think the majority of us would ever have any issues other than . ad targeting.
