Shel Israel for Forbes:

There was once a Golden Age of social media, when people talked about the ability to find useful, interesting, valuable people to talk with all over the world. Businesses of all sizes discovered that there was great value in listening and engaging with customers and other relevant people. What had once been one-directional monologues became two-directional dialogs and most people saw that it was good.

Then the marketers got their hands around the throat of social media strangling engagement and stuffing messages down its throat.

I agree with almost every word.
