I think attributing the insertion of Lou's name and podcast to a deliberate cross-marketing and/or kickback from Disney corporate shows a profound overestimation at the amount of care that Disney/Marvel does, or even could put into their thousands and thousands of products.
The only reasonable explanation for this as far as I'm concerned is that one of the people involved in the writing of the comic needed a fake/amusing name of a journalist and a media outlet for a throwaway line in a single panel, and since the artist just happened to be a fan of Lou's show, decided to give Lou and the show a shout-out by namedropping him in the comic. As has already been pointed out, it's very common for comic-book artists and writers to hide subtle references to music, movies, and books they like in their work, usually in a way that only a fan of the referenced work would "get it." This time it's the Disney Park Internet Community, for what it's worth, that has a chance to "get it," and here were are tossing out bizarre conspiracy theories.
BTW, it took me about 4 minutes to find that the comic's writer, Dan Slott, is something of a Disney Park nerd himself.
I'd say that the possibility that he's downloaded and listened to a few shows of most popular Disney World podcast is fairly high.

To allege some sort of cross-company effort to besmirch what Brett in his show bewilderingly called a "sacred" piece of pop art with Mongello's name is attributing far more effort initiative and craftiness than Disney Corporate is capable of.
The reality is, the only one who cares about this is us, and, assuming he even remembers doing it, the comic book writer himself.
