I have started to put a clause in my own contracts that's paraphrased like so: I do some work for you and submit it to you for verification. You have x days to verify it. If you fail to verify it or tell me a scheduled date for verification by that date, it goes on github for the world to see and use for free. I.E. "F* U, Pay Me."
Interesting approach, but what stops the client from using this to his advantage? "Hmm, if I fail to pay, the code becomes open-source, and then I can use it for free."
Depends on how much they want to deter competition. This particular company was a hardware video switch; competitors could easily port the same app to their machines and then the client loses the advantage they had previously.
