When I did a little project using jslinux, just for fun on the Chaos Communication Camp 2011, I contacted Fabrice about it. And he was helpful and gave permission to do with the code what I planned to do (I wrote a network hardware emulation, the corresponding Linux driver and a central server, so I could connect to the remotely running Linux instances in peoples' browsers). It's allowed to discuss Fabrice's code, it's allowed to post a de-obfuscator software tool, but it's certainly not permitted to publicize a derivate without his consent. It's plain respect for intellectual property.
