Facebook enables people all over the world to connect in ways that protect privacy,
Facebook ignored users privacy settings and allowed phone manufacturers low-level access to users FB data.
I found out about this 2 years before it was reported by the New York Times and had contacted the manufacturer of my device multiple times by both email and by phone yet the representatives vehemetly denied they had access to users social media data.
Multiple requests to view what data had been collected by the Chinese manufacturer (as per the privacy policy) were ignored even after multple escalated phone calls and emails.
I also found that the factory installed Facebook app could update/modify itself remotely without using the Play Store.
After witnessing all this I deleted any and all social media accounts and set about learning how to better protect myself and others.
So, fast forward a year or so to the Cambridge Analytica fiasco and I see Mark Z. lying through his teeth to Congressman about the extent of the privacy abuses.
And now senators are asking more questions about the location controls on Facebook:

So, if any of you congress critters are out there, ask Mark about his "Facebook/Places" portion of his SDK's he gave to millions of third-party app developers that use WiFi, Bluetooth and NFC for location above and beyond the devices GPS.
Facebook sold out the privacy and security of the entire nation for an advertising dollar and it will be our undoing.
