Edit: Why am I getting downvoted? It's a simple question, IANAL.
It makes sense for TC to reveal them: this deprives FG and its PR-firm cronies the opportunity of spinning them the way they'd prefer, and is probably just good business in terms of TechCrunch's core business of selling eyeballs to advertisers. (It got me to visit their site, which I rarely do, FWIW.)
I’m embedding all the relevant documents below. A lot of time has been spent by Fusion Garage’s lawyers to try to keep these documents under seal, but they have recently been made publicly available.
I imagine that they wanted the documents kept private because they make Fusion Garage look very bad. Even if they end up surviving this lawsuit, I do not think very many companies will want to work with them.
(On another note, I'm going to assume that FG knows this information exists and can be found/subpoena'd. They should already be preparing to defend themselves against the information in this release.)
Arrington wants to win in the court of public opinion, and he wants to wreck Fusion Garage. He wants the people who made the decision to bury him irrelevant to the Valley. This was his baby, anyway. Not that it wouldn't have been crushed by the iPad and all the johnny come laties.
