Environmental Working Group getting percentage of sales of products?

First came a shocking bit of insight into how EWG racks up some of its revenue. For example, EWG annually evaluates sunscreens, rating them on a 1 to 10, best to worst. I clicked on one of the top-rated sunscreens, which I’m sure is a fine product. It must be, as it not only provides UVA/UVB protection, it’s “gluten-free.” (No, I’m not making that last bit up.) I scrolled down the page and clicked on an Amazon link that would have allowed me to buy the product. What people may not know, said Hayes, is EWG gets a chunk of change when you buy through Amazon. It’s not insignificant either.
