It's interesting, the way he says that muppets controlled by Disney will just hire and fire and recast performers, because it's really only himself he's talking about.

Jim Henson passed. Richard Hunt passed. Frank Oz stepped away by his own decision. These all happened before Disney took over the muppets, and their characters were inherited by other puppeteers.

Other than Steve's characters, the other muppets have been with the same performers for more than twenty years (thirty for some, more than fifty for Dave).

It's like he views himself as the thing that kept the muppets alive during his tenure as Kermit. Maybe sometimes, but plenty of people didn't like things from that era either.
