The real problem with FB is addiction. People especially kids get a shot of dopamine for every "like" on social media. It is also an escape from reality and it is possible to carry on a fantasy life. This experience isn't going to end well.
I quit for the third and final time a few months ago. My kids text pics, etc. We have a group family text thread. I don't like being tracked and my data being sold. Facebook is a very negative social force and a conduit for misinformation. So many fools that believe the "news" they read on FB.
