The $350,000 figure was substantially more than the $150,000 I heard when I asked last. Wow lawyers are expensive. Internet Brands should have paid for all of the expenses IMO but in the USA pushing for that is sort of like playing double or nothing. 

I donated $10,000 to the WMF to help cover these costs. We managed to return a travel wiki back to being free and open. Thus many thanks to all involved.
