He's not going to explain because he can't explain. No one here has been able to explain it.
At some point shorts must cover unless they own shares long. Given that on average shorts have taken a substantial hit over the last year, it is not rational to suggest they are controlling the price.
The shares short don't control or affect the price and neither do shares long. Only dynamic shares, those bought or sold, affect the price. So, if Seth has an explanation, he should be able to lay it out by example, not even mentioning SODA or any particular hedge by name. Just use A, B, C, X and Y.
