Just to chime in here. It seems that every Theravada buddhist teacher is gonna have some people in the Theravada who don't like the way they teach or think that what they teach is adhamma. How many really are teaching against what is dhamma is another matter that I don't have any answer to but I'd just point out that I've read criticisms on this forum leveled against Mahasi Sayadaw, Goenka, Thanissaro, Brahm, Vimalaramsi, Ajahn Chah, and probably some other teachers that aren't coming to mind right now. So I'd take any criticism you read here with a grain of salt.
