Why must you forbid this? If someone is a good enough marketer to sell to idiots, that's his own success. It's not like he's stealing from you, people can and will use your software if it's good. If someone takes your software, makes a GUI for it and sells it to idiots, it's his own damn right. What he's doing is not infringing on anyone's freedoms, he's just suckering some idiots, who would have been suckered on other things, if not for your code.
