BET is a whole other issue and there were a lot of hands involved in BET's current state, however you feel about that positively or negatively. If anything I think you should direct your ire towards former owner Bob Johnson.
That being said, Hudlin's desire to expand the audience wasn't a bad thing. That's what each writer of Panther has tried to do, with the most successful being Priest and Hudlin. (I was a kid during the McGregor-Kirby days so I don't know how successful the comic was during the 70s). So Hudlin's 'dumbed down' approach did work. I do think that Hudlin tried to expand his audience to people of color whereas it seems that Priest, Maberry, and Liss's stories seemed to try to corral more of that dwindling number of white fanboys.
And what's wrong with marketing something for Black History Month? A lot of companies market things for Black History Month and a variety of holidays. Comic companies included. Now with that being said I think the marriage was something far more than a mere plot to exploit Black History Month. I think the wedding had wider reverberations throughout all fandom. And Hudlin gave us comic's first black supercouple, which was an amazing thing. The idea of black married supers being front and center was something we hadn't seen much of at either DC or Marvel. It was a very big deal, especially when you consider all of the negative media about the state of the black family. The Storm-Panther marriage was a powerful statement, an affirmation of black love in a media that often ignores if not outright distorts it, and I am glad that Hudlin and Marvel did it. And Hudlin didn't pull it out of his hat, there was some precedent for Storm and Panther being together as I've written before. I don't think Hudlin sold either character out. I think he set it up for Marvel to take them places they hadn't been before. The marriage opened doors for both characters. If not for the marriage, would Storm have gotten her miniseries? Or even joined the Avengers? Or had as prominent a role as she has had thus far in AvX? And conversely with T'Challa, would he have been involved in any of the X-Men storylines or mentioned as much as he is post-marriage throughout the Marvel Universe?
Sorry LS, but just about everyone in the comics business is a capitalist, and the bottom dollar is the most important thing for them whether they want it to be or not.
People continue to hate on Hudlin long after he was off the book. But are pretty silent about Maberry and Liss who had far shorter runs than he did. Hudlin's run upped T'Challa's profile in a way that none of the other writers of the modern era-even Priest-did. And Panther approached something close to mainstream success, with the wedding and getting a cartoon, and now being in the Marvel cartoon movies and on the Avengers. I think it's time to stop hating on Hudlin and give the man some credit, whether you liked all of his decisions or not.
Even he admits that he didn't always bring his A game to Panther, due to his other commitments, but still his work has been an integral part of Panther's current relevance.
