Patents are another issue. Doesn't specifically affect this project.
And clean-room implementations have no effect on patent violations or claims. None at all. It is entirely a copyright issue. And the issue here is that the same person who disassembled one codebase then wrote a new, equivalent codebase. Thus the new work is a derived work, or at least a lawyer can argue that easily, and thus distributing it for profit is a serious crime. Not even a civil offense, in any EU country. Criminal.
