I think that last line is getting to the point more than most of the discussion I see.

The host of the show doesn’t really decide what he’s going to say. He reads the script the writers deliver (with his approval, I’m sure). He’s the talking head of a production team.

Jimmy Kimmel the person didn’t get taken off the air. Jimmy Kimmel the show did.

That makes it relatively easy to go back on the air, if they simply give new direction (constraints) to the writing team that satisfy the network.

If I were to guess, I doubt Jimmy Kimmel the person cares what the team is or is not allowed to write in the script.
