Hang on. Which one are you trying to say is right or wrong?
As far as I can tell, everyone should hate string theory, or at least the failures and pathologies of the scientific/academic system it has come to represent.
String theory specifically is an extremely rich and fruitful theory that has had huge application to mathematics (mirror symmetry, no ghost-conjecture and the mysterious moonshine etc.) as well as inspiration for theoretical physics (AdS-CFT, Supersymmetry etc.). It is telling that none of the loudest voices telling people to "hate" an area of theoretical research have studied it (or often studied any physics or math, since the technical details, or even a grounded understanding, are superfluous to their "arguments").

I'm saying they are both wrong
If you want to hate something, hate the pop-sci articles that sold it as a "theory of everything" for 20 years, and hate the environment that made it neccesary for researchers to peddle that bullshit in pursuit of funding, don't dogmatically hate an entirely valid area of research just because some mouth pieces who peddle narratives of a very technical field to an audience who aren't able to meaningfully engage with it, have decided to turn against it (i.e. Sabine hossenfield and eric weinstein or whatever their names are).
