Not a cyber truck fan at all, but not sure if this tells us much. I can't see any scenario where force is applied to a hitch in this manner when you are towing.
Think about how a trailer is framed. Typically x2 side rails coming together in a Y at the tongue. If you are going to apply a 10,000 lbs tongue weight to a hitch it has to come from somewhere, meaning that you would have to come up with a scenario (say heavy braking) where a load shifts and transfers through the tongue beam and applies a 10,000lbs load downward on to the hitch. That's just not how towing forces are applied - the trailer tongue beam would bend into a noodle. Force is transferred straight through the trailer frame and applied to the hitch in a forward direction. The rear might squat a bit under braking, but its the forward force that the truck needs to manage.
Compare it to something reasonable like an F150: Max towing capacity starts at around 7500lbs, with nothing fancy - once you start going through the engine/tow packages you can option it up to 14,000lbs. That's about the max a 2" receiver can take in any configuration. In that setup, max tongue weight according to Ford is 10% / 1400lbs - that is absolute limit, typical recommended tongue weights are in the 500-800lbs range. In no scenario are you getting 10,000lbs of tongue weight applied directly to the hitch in the manner shown in the clip.
If you were seeing a 1000lbs static tongue weight turn into a 10,000lbs tongue weight under heavy braking you would be popping tires, bending trailer frame, cracking springs.
If you want to beat on a cyber truck with an excavator - just do it for fun / monetize the clickbait - don't cosplay scientist.
