Anecdotal, and not the GP, but one of the interview questions I ask is "If you could uninvent one technology, what would it be and why?"

Many of the answers are the same: Facebook. At least for developers, Facebook is generally seen as a net negative for the world in it's current form.

It's less about proving a point and more that I have it blocked at the router level because I don't use Facebook myself and yet they still use the domain to serve tracking & stalking scripts which are malicious.

What do you mean by "reactionary" here?
