Lets say there is a piece of commercial software for vB4 and it is not available for XenForo. If I bought the software then hired a coder to make it work with XenForo (I don't even know if it possible or not) to me seems unethical. On the other hand the software would be paid for by me and the coder that modified it would be paid by me as well.
I can argue that I bought the software and can do what I want with it.
I can also argue I financed someone to work on someone elses software and the coder might start selling the modified version of the software cutting out the original coder. That to me would be very unethical.
If this is unethical I will not go down this path.
What are your thoughts on this.
