'course it's not just him, but it's him and _everyone else_. i'm not sure what their overall intent here was, but it's been a shit show from start to finish, and they gotta at the very least start thinking hard about pausing the rollout till they can get their ducks in a row.
If they wanted him to pay $20 million, they'd certainly have given him much better than a brief phone call.
But that's the point. They're revealing with their actions that they don't actually want him to pay the money. What they want is to shut it down. Charging a sum of money that they know he won't pay is just an easy way to do that.
