Recently had a similar, but likely more severe problem: I noticed Sol decompiled some proprietary code to re-implement some functionality for an emulation I wanted to use internally.

Now its likely soiled and I have to throw it away. Doh! I asked it about legality and it went "its almost green" but when googling, reverse-enginnering like that seems very illegal.

The weird thing is in this case, it could have pretty easily gotten the needed info from using the code as a black box, and that is apparently legal!
