Help this fella!!

So a little bit of context, I used to do Radio( Radio Presenter) and enjoyed that time alot. There was another RJ who's quite famous educationist and artist and ambassador of a university, he's offering me a campus podcast for that university, in which am quite interested but I have a feeling that it's a betrayal to my own university as I will be representing and highlighting the positives of another institution, help this fella out, your suggestions will help me make a decision.
