Show HN: Open Letter Explaining our Frozen Campaign

Background: CentUp's Indiegogo campaign reached its goal of 15k raised (from 500+ donors) with ten days to spare. On the same day our campaign was frozen due to a complaint from someone alleging we were infringing on their patent (we're not). It is policy of Indiegogo to freeze any campaign until the matter is resolved. Anyways, this is the letter we shared on our site. I'm curious to get feedback on tone, transparency, and clarity. Thoughts? Letter is up at centup.org
