They're good questions and would likely depend on how already invested one is into Facebook. You completely leaving it (for example) would probably not have as great an effect as me leaving, guessing on the fact that I've used it quite a lot over the past x years. For those who are light users - my best guess is that they'll either not see the problem and continue, or switch to a more addictive platform (Twitter). You might choose to hand out a not-Facebook contact detail or alternative preferred method of events notification and this will probably contribute something to nudging another person toward a particular direction (if it's as simple as handing out a secure chat app and letting others know they exist, that could be a good thing) For moderate and heavy users, they might deactivate and then delete Facebook and learn from that experience and then be wary of all social media from that point on and choose to go outside more to ride a bike in their local area, etc. It's all worth considering.
