If you look at the DigitalRev website you'll see the product widget in the side bar[1], this lists the products they have for sale relevant to the article. Why would a GoPro employee be looking at digitalrev.com? Probably to look at reviews of their products. If they were on that review page and spotted the GoPro being sold with unlicensed images (or whatever the problem is) they're likely to link to the page they were looking at when contacting their lawyers, correct? This seems like an unfortunate oversight; the person that "discovered" the GoPro licensing issue linked to the page they saw it on, not considering the potential confusion because they're linking to an article about GoPro.

Seems like an easy mistake to make.
