Imagine the case that you do an unpaid internship for a company and in one of your meetings you give them an idea for a future working direction. Later you leave company and continue you professional life somewhere else. After some time you read about the company in the news and see that they have employed your idea and became really successful. Should you ethically have any right on the idea you gave away even though you didn't know it would make the company successful at the beginning?
(using utilitarian ethics)
