Consider the following chain of events: - I write GPL'ed code. - Someone uses this tool to develop a proprietary solution. - I later prove that the tool generated code that is equal to mine. Now the code of the proprietary solution must be GPL licensed! Cool! How I'd defend myself? I'd only use such a tool if there are guarantees of the licenses of the code it was trained on. Without such guarantees, it is just too risky.
