Lol you ****** end to end encryption is 100% safe for privacy well how should Facebook know your end to end encryption key? Right they can't so they can't read your messages. If you're going to put something in your status then yeah Facebook will see it too but what does that get them? Why spend thousands of dollars on processing cost just to get some informations for ads for someone? Right they don't do it. So basicly just leave your GPS off then Facebook won't see anything
