Rabbi twersky was close (and related) to many gedolei torah. His rebbeim encouraged him to go into psychiatry, and for good reason – he saved many lives and was a profoundly good influence on people.
As far as i know, he did not submit all of his opinions and writings to daas Torah. He wrote in his sefer on chumash that he’s not a daas torah, and that one can only reach that level of torah by learning day and night exclusively, without being involved in other things. He would not shy away from legitimate criticism.
I’m not saying anything revolutionary. He has a chiddush in how to approach the yatzer hora which is not the way baalei mussar and chasidus teach. He’s not saying apikorsus or anything horribly bad. It’s just a mistake that came from his line of work. and if people do less aveiros, or work on their middos from it… it’s a net positive But it’s not the mesorah.
