A research magazine with a masthead of three names and no legal entity, whose reports keep finding that the founder's own products are "Rated Highest". It published a good exposé of one network while running a smaller version of the same trick. The about page admits the commercial interest in one sentence and then claims there is "no rate card for inclusion", which is true in the way that matters least.
In their own words
Trellner Research has a commercial interest in several products and datasets that appear in the magazine.
