The short answer is - AR15 is a business and charges dealers and manufactures to advertise their products. We were not advertisers, but gave advice and talked about our products. That harms their business model and upsets the companies that do pay for ads on their site.

Selling ads tends to have this effect on forums - causes some awkward situations - because it makes a forum have to tell some people but not others to limit what they can say. That is why on silencertalk I just have google ads - to avoid having to tell people in the industry they cannot post a video or something about their gun because it is promoting their product.

There is a thread on it here:
