Zuckerberg is, and was, especially after the movie came out, much more famous than Weinstein, and the portrayals in question are different. One is unflattering, the other is attempting to cover a felony. When there's an unflattering depiction out there of you, bringing more attention to it might be counterproductive, depending on how bad it is. If you're worried about going to prison, all of a sudden how unflattering you're seen likely becomes secondary to that.
