I don't think punishing people for suing you typically plays well in court. Especially not if you, you know, publicly announce that's what you're doing.
This was my reaction as well. This sounded like tortious interference before, but to blatantly announce that he’s trying to kill someone else’s business, for exercising their legal rights no less, sounds like a summary judgement waiting to happen.
There is no dispute over the facts here if Matt is just going to announce his intents.
I cannot imagine his rage when not only does WPE not have to pay him, but now he’s paying them.
