The important part:

“The letter that was posted next to the review on DigitalRev was not sent in response to the review. Obviously, we welcome editorial reviews of our products. This letter was sent because DigitalRev is not an authorized reseller of GoPro products and they were using images and had incorrect branding and representation of our product in their online commerce store. As part of our program – we ask merchants who are selling our product to use authorized images. That is why DigitalRev was contacted. But – our letter did not clearly communicate this and that is something we will correct.”
