I'd argue that in the pursuit of upping engagement, they've shifted to pushing our buttons too much over the past year or so. Or at least that's true for MY buttons.

Over the past year my view of Facebook has shifted from "I kinda don't like the privacy implications, but it is very useful for following what my extended family (most of whom live literally across the country) and friends are up to" to "why is this fucking thing sending me all these useless notifications all the time? (rhetorical question, I know why it is...) am I getting enough benefit out of it to be worth all of this or should I delete it?"

YMMV.

I was referring to employees in the last paragraph. I agree that users will probably not leave, unfortunately.

I very much doubt that most employees at Facebook share your viewpoint that Facebook is a net negative for society. It’s almost a tautology—people who feel that way won’t seek employment there.

Yes, and I’m hoping that these “scandals” make people reevaluate their previously held beliefs.

Some employees probably feel that they can help move things in a better direction.

surely then there ought to be nobody who willingly works at a tobacco company!

my relationship with Facebook reminds me more of an abusive girlfriend than one which is on the whole good
