@EliJelly Your claim that the mass shmad in Europe was a consequence of Mendelsohn is not necessarily true. In Germany, the shmad happened virtually overnight, without any haskala. People weren't maskilim, they just became regular non-frum Jews.
I read the Teshuva from the CS in Darkei Hora'ah and he treats the Maharitz Chayes with the utmost respect. And he does not mention a word against Haskala at all, only against publicizing kulos because the hamon am, i.e. the amei haaretz, will misuse them.
Haskala was not the issue at all in that part of the world.
