Open letter to warez sites by mobile app developer

master_p writes: Alex Kac, CEO/Founder of WebIS, a small software company which makes mobile phone applications, has posted a letter to warez sites explaining how WebIs is deeply hurt by software piracy. Other mobile developers strongly agree with that letter. Alex pretty much begs warez sites not to copy their software, because otherwise he will be forced to close down his company. Big companies like Sun or Microsoft are not really hurt by software piracy, and they have occasionally been helped by letting their products copied freely (and illegally) by almost everyone, but what about small software developers? Is it viable for a small company of under 20 developers to live on writing closed commercial software? And how will warez sites respond? finally, how will RIA/MPAA/SBA can offer protection of small software developers, if any?
