Ok, i've used that DLL and know for a fact that you can get the source code, As it says in the Readme.
If a person isn't willing to read the readme, What makes you think they would read source code, Let alone compile it?
I'm sure when this guy posts a link people would happily download his program, And run the binary, without so much as a glance at the source code anyway. Where is the sense of security, really?
