Maximillian had no involvement or even awareness of this. Arcade1up piggybacked off of what he started without his involvement or awareness. He even talked about this when it got announced. He was both excited for it and kind of mixed on it seemed like, as he's promoted their products in the past and is friends with Justin Wong (who most likely wasn't looped into the business aspects of this like exclusivity).
I think Maximillian kind of all but explicitly said that what they're saying is technically true but not necessarily in the spirit of what he was trying to accomplish? He's looking forward to it and planning to get one but also I don't think he necessarily considers the job done until MVC2 gets a new PC/console release. I don't want to put words in his mouth as my memory is bad so you can watch his reaction to the announcement if you want:
