Hasbro trying to endorse toys is the basis for the entire series, so try not to judge it too harshly.  Yes, there are times when the ploys are handled somewhat poorly, like the Breezies, or the Equestria Girls line, but that’s not the point.  Don’t get mad at Hasbro for trying to make the money that helps keep the show on the air, instead feel proud of the writers and animators for being able to put up with Hasbro’s marketing ploys and ideas and still managing to put out enjoyable episodes.
