Are there two of them?

I heard, and have seen, some very negative things about the AWAI Michael Masterson and his product/company BUT I also hear about a Michael Masterson highly recommended by people I trust.

Based on what I know about the first Michael Masterson, I am dismayed to see folks I have trusted to this point, claim that Michael Masterson is one of their closest associates. I'm wondering if they are one and the same Michael Masterson or are there two different people with the same name on the internet?

Thanks!
