At my last job, our product depended on an open source project by one of the company’s former employees. I came across a massive bug in our code base that was related to this open source project. Despite the fix for the open source code being like 3 lines, management kept saying, “but we don’t want to help our competitors who might use this.” (No one else used it.) At one point, management asked me why don’t I fix it off the clock because then it wouldn’t be “company resources going into an open source product”. My response was basically “fuck you, pay me.” It took me a literal month to finally convince management.
