The Satmar Rebbe, Rabbi Yoel Teitelbaum, once explained he doesn’t tell Chassidic tales because “one cannot educate with lies”.
I found a wonderfully brief polemic titled “הקדמה לספר ויואל משה החדש”. The pamphlet points out a tiny bit of the blatant lies and misquotes and factual ignorance and shoddy scholarship throughout the overrated Vayo’el Moshe, and does so in attractive fashion (following the lead of this work).
Well?!
For examples of knowingly untrue presentations by Vayo’el Moshe, see the ongoing series devoted to VM in Kedushas Tzion.
