It’s fraud. They publicly claimed, point-blank, to do a certain thing for years, and were instead doing the opposite, in the interest of making more money. The affiliate link thing is only one of several points that they’re suing over. The far more egregious one is that they don’t actually “scour the internet to find you the best coupons” They will actively hide better coupons that they know about, if marketplaces pay them to, and still tell you in the browser “this is the best coupon.”
House M.D. Season 7. Love the show, myself, I put it on for a rewatch while working every couple years. The medical stuff ranges from really interesting to utter nonsense, but the character writing is pretty great, throughout.
