Guy writes some open source code and puts a license on it saying others can use it as they please. Someone else uses it. Guy goes on Twitter to complain someone used it without credit. In response to rant on Twitter someone points out that there actually is acknowledgement in the code. So in the end, they used it and gave him credit. Guy is like, oops, well that’s cool. Sigh.
