I have to come down on Jon's side. He has the contracts and he has the dates he has to fulfill. He and the rest of the band, and the huge crew needs their lives to go on whatever is happening with Richie. And Richie has not been reliable lately (since 2007 at least).

That said, as CEO (or quarterback) Jon has handled the publicity for this problem very poorly. He alone is the responsible party for the PR debacle.
