I have noticed that some developers use ready made open source code from github and other sources and sell the code on codecanyon. Some claim they add some features like admob. Others just modify the source code a little bit. I know that because I purchased an item on codecanyon and i found that it was an open source code.
So I have some questions: What is envato policy on this issue? Is it ok to sell open source code projects which are available on github or other sources. If not can customers report such items on codecanyon?
