Perhaps you should write to Mr. Atkinson and express directly to him the concerns you are raising here. I quit reading magazines long ago so have no sense of the current editorial tone of Stereophile. If the staff is obnoxious on other fora, that doesn’t reflect well on the publication in my estimation. I do believe that disclosure of professional or commercial interests is appropriate, but if you say that Atkinson is not even-handed in imposing such requirements, you should bring that to his attention as well. Do they still publish a "reader" "Letters" section?
PS: I think the real danger in not disclosing industry or commercial interests isn’t necessarily the heavy-handed sales pitch, but the presentation of information, as such, without revealing possible bias (or the appearance of bias). I don't think such bias is a foregone result of an industry or commercial affiliation. Valuable information can be provided by those involved in product development, particularly since I doubt there is much funding available outside of industry applications for such research. It would seem to me that any one in the industry or with commercial ties to it should also use their real names (unless there is some 'whistleblowing' aspect to their activities), but perhaps I'm in the minority.
