Just so everyone is clear, I very very rarely go to Facebook. I've had an account since 2008 or so and had to have it when my kids were younger because various clubs and groups that they were involved with posted updates there.
I never used it heavily in the early days -- even then it felt like a time-suck. As a designer, I started to realize the techniques they were using that leveraged my innate psychological wiring and left me susceptible to be unconsciously led where they wanted. I stopped using it somewhere around 2012-2013.
What surprised me (and I'm not easily surprised) was 1) how aggressively they served the content and 2) how egregiously false the content was. The two posts I shared were only one post in the feed after the top post that I went to view (which had NOTHING to do with KU, Basketball, etc.). They have picked up information about my interests from God knows where and are thirsty to rouse my attention and get me to click. I mean, this is content that says that someone has DIED and that another person has some life-threatening health condition.
That's pretty low. I guess there is no moral line these days.
