Did the studies show a negative impact in any meaningful sense, though? "Some teens report that Instagram contributes to or triggers to mental health issues" is my understanding of the most supposedly-damning finding; I understand why this can be turned into a high-engagement news story with (at best) genuine ignorance on the part of journalist and editor about how hard it is to defensibly turn survey results into interesting causal psychological claims or (at worst) mild deception, but I really don't think it tells us much about whether a world with any plausibly different Instagram or no Instagram at all would have less extreme or less frequent mental health issues in teens overall, or even in many of the specific people who report these problems. I don't think declining to publicize the results of an internal study that will be predictably grossly over-interpreted by media and therefore by the public is actually wrong, and I read the FB response you posted an archive link to as saying "this research has been grossly and selectively over-interpreted", not "this research isn't very good".
