This sucks because of all the fan videos I've seen Jan Animations is consistently the best out there. Everything from the writing to the art design the characters and animation is up there with the show itself, and I guess right there that is the problem as if you didn't know then You could easily confuse JA's content with Hasbro's content. (Not something you are gonna do with 'Smile HD' for example).
I hadn't twigged the Button was an actual character from the show (albeit a background pony) so when you rope in the plans for an entire series of button videos I understand where Hasbro comes from. JA,s videos are just too professional and getting to close to an actual product for comfort.
I would have preferred if hasbro has just taken down the button vids (leaving meet the Bronies, picture perfect pony... Ect) but when media companys wield the C&D axe they tend to swing it wide..
I would add that most of his vids are hosted on other channels so grab them wile you can....
