The fundamental question regarding the article is: Can these scientists afford to be honest? Can you do research that shows spending time on FB is bad for people and be allowed to publish this information?
On a superficial level, they seem to be honest. They start with the bad news, admitting that using FB the way many (most?) do makes them feel bad. But they counteract it immediately saying if you interact with others, you'll feel more happy.
You can overlook one critical difference. What FB makes you feel and whether FB is good for you are two different issues that may or may not be related. You may feel negative emotions when going to a doctor but it's still good for you. You can engage in endless chat online, but is it good for you? It's much harder to answer.
