Facebook is good for some things, not so much for others.
As a guy who got into the computer industry back when computers still ran on vacuum tubes, and fixed electric typewriters for a living before that, I think we A) have short memories, and B) are averse to change, especially us older ones. I was an Internet holdout myself, until I moved up to Central NY.
What folks are saying these days about FB is essentially identical to what folks were saying a couple of decades back about the Internet; and with respect, the Internet is a lot different now from where it was then.
I think that things improve over time. FB needs a bunch of that time to find its best direction. Not there yet, but if the Internet itself is any indicator, it still can hold promise.
Nobody rules the Internet, and will have Hell to pay when they try; but basic capabilities were the main restriction to its potential back when. Same-same for FB right now.
Give it time.
If we want to deal with Gun Rights Oppressors, there are better and more immediate subjects for our attentions.
