alt Hacker News> So what about SO code snippets?
StackOverflow snippets are mostly licensed under CC BY-SA 3.0 or 4.0, so I'd wager that they are not allowed, either.
The SDL source code makes a few references to stackoverflow.com, but the only place I could find an exact copy was where the author explicitly licensed the code under a more permissive license: https://github.com/libsdl-org/SDL/blob/5bda0ccfb06ea56c1f15a...
Most SO snippets likely aren't unique or creative enough to count as works. If a hundred programmers would write essentially the same snippet to solve a problem, it's not copyrightable.
