That's a very hyperbolic statement. Facebook still has merit as a way to organize and communicate with your social group, even if there are some negatives. For cigarettes, I don't know what positives people can claim with a straight face. That you get to go outside at work for a smoke break?
I really wish I didn't have to breath the Facebook's (and Google's) secondhand smoke every time when I interact with other people (or websites). Just like smoking, putting a "like" button on your website or using any of their services to chat with someone inflicts causes "secondhand" damage on people that choose to people that chose not to "inhale".
> I don't know what positives
Nicotine is a drug. It should be obvious that some people enjoy its effects and/or find it useful. The tolerance effect may reduce those benefits for some (most?) people, but that doesn't change that it had (or continues to have) positive effects.
> claim with a straight face
Maybe you should ask the doctors at the Harvard Medical School[1] et al about the benefits nicotine seems to have for several mental health issues? Now that we are finally moving oast the taboos on any nicotine-related research, these discoveries might lead to entirely new types of medication.
