I don’t know him and can’t give him a reference but with notable exceptions (including recently) I don’t remember him being the target of criticism about Tmmi’s direction and failures, other than - ironically - the view that as a geotechnical engineer he would perhaps be better suited to work at an oil company and not in tech.
International Royalities is - transparently - his management company. Up to him of course to decide whether to sue the living bejesus out of anyone who defames him.
