You can't go around dismissing scientific studies just because the authors have a conflict of interest. There's almost always a conflict of interest in any scientific study. For example in most studies there's an "interesting" result (e.g. method P works, X causes Y, Z is a real phenomenon) that might come out or a "less interesting" result (method P doesn't work, X has nothing to do with Y, Z doesn't really exist). The interesting result is almost always better for the scientist's career.
