Contextualised as in saying these are "The best", rather than just saying "A list of"?That's how Polygon describes marketing content. You won't find them refer to it as sponsored content anywhere on their site, presumably as it's not a direct advert, but instead a 'partnership' that they have with particular sites and companies. As I said, it's not editorial content. It's just a list of deals with a blurb at the top. 'Editorial content' would be if they wrote a review of those items, or contextualised it in some other way,
But look- if you think you have some sort of 'big story' here, about how big union guy Ben Kuchera is not so secretly shilling for Amazon, and that Polygon show the excesses of gaming journalism with no clear line between their editorial content and their marketing content, why don't you email Jason or someone similar? Surely they'd want to run such a big story?
Ben Kuchera exhibiting poor judgement is not a big story. It's not news to anyone who has been paying attention.
