I've figured it out! George has been using a combination of steganography and subliminal messages in the PT that have successfully brainwashed legions of viewers into becoming hypnotized zombies that support his SE changes. We escaped because we don't like the PT, and therefore haven't watched it enough to become victims.

The humdimger glitch is not an encoding error, but a desperate encoded cry for help from someone in LFL who, in a brief moment of lucidity, hastily inserted a plea to be rescued. I have decoded the message and it says: "please help, send troops, I am being tortured at Skywalker Sound by being forced to insert George's new effects into... into... blbqwggw... "
