@seanheis1 -- I think you are confusing "permission" from a company for a review with notifying them, the latter which is perhaps more common with the "influencer" crowd that generates money from views and the traditional audio web sites that often started as magazines. To my knowledge, ASR has never asked permission or given notice to a manufacturer prior to testing an item, though they have often interacted with a manufacturer after the review has been posted. I don't think any other company has reacted the way Tekton has -- it is Tekton's behavior that has caused the fracas, not the review itself. As noted before, it was a complete non-issue for months after the original review.
That said, I'm content with what's been posted in this thread and those reading are free to draw whatever conclusions they like.
