The assumption is that engagement = good for business. I personally believe it isn't, as I've personally quit all social networks (notwithstanding HN and a few private communities) because they made me addicted and unhappy. Unhappy users stay because they're addicted, and a part of them quits. Happy users stay because they want to. Not making people unhappy is good for business. Or at least I hope it is...
