Avi, do you think that there was this massive movement after the shulchan aruch, that literally everyone stopped sharing ideas with philosophers and only the maskilim kept the “mesorah”? Rav Hirsch opposed learning any philosophy at all, though he clearly advocated learning science, language, history and other studies. I know of no accepted acharon; be it from Litvish, Hungarian, Sefardi, Chasidish, or otherwise, who felt that hashkofa was a free for all where we should mix in with goyim.
The chossid yaavetz writes that during the inquisition, the only jews who stayed behind and became marranos (hardly heros… They broke halacha openly) were those who were involved in philosophy.
