Just because they've changed something, doesn't mean it's positive as your making out.

Secondly, I've seen engineers running around with Facebook shirts on with the slogan "Connect the world" written on them, I would find it irritating if I couldn't see the irony in it, instead I just find it funny.

There is a lot of cognitive bias happening with people working there. They wave big money carrots to keep staff and I feel for some people it's a way of validating their ability, so they stay no matter what impact the product is having on society, even if they don't agree with it inside.
