I think that's a flawed comparison, at least for some people it has a negative impact (as opposed to simply not being useful enough as a tool).

I've actually derived a lot of value from Facebook in the time that I've had it, but I left as an experiment with my mental health and it's genuinely helped me.

Also, not being able to control it is hard to blame on the end-user when Facebook designs aggressively around engagement and hooking users in by virtue of psychology.
