I would assume not, unless it is brought into the DIS network due to it being a conflict of interest, he most likely has something akin to a non-compete clause in his contract.
He does some social media with his Facebook group, but I don't think he does videos outside of the DIS now, unless they are guest appearances on other shows. I could be wrong, though.
I would expect now that he works for The Dis, you won't see his Big Fat Panda content anymore, but it will be part of The Dis. I think he is fun to watch and adds to the show. A good addition.
