That's somewhat unfair.

Facebook doesn't give you (and people around you) cancer.

Facebook doesn't cause cancer of course, but there's no shortage of evidence that it harms some of its users, as well as contributing to social phenomena that harm non-users. The Rohingya genocide is a prominent example.

Hard to compare, in terms of what is worse, cancer or depression but I am also surprised more people didn't write here.
