It's not the host. Legal wanted to kill the show after 2016, but the event team made a case to bring it back for the "Farewell Tour" with Bill & Ted again--after, as I understand it, many, many rewrites. The issue wasn't the hosts, it was the use of other companies' IP, even in a "parody" setting. There's a reason the show used a dozen "Camera Nazis" and told them to be overzealous.
Long story short, we're not getting another pop culture parody show that incorporates other company IPs.
