I have searched everywhere and have not found the answer to this specific question.
I know someone who recently designed and coded a small responsive website for a paying client.
A few days ago I was going through some web design tutorials and discovered that this website is an almost 100% copy of the code of the example from the tutorial, and some of the graphics are identical. To add to this, the person put their own copyright notice in the footer.
My feeling is that this is wrong and very unethical but my question is: should I approach this person about it? Are tutorial examples copyrighted? How much trouble could the client and the web designer get into if the person who made the tutorial discovered the website and took exception to it?
I sometimes work on projects with this person, so I want to do the right thing but I do not want to damage our business relationship if at all possible. But this really bothers me.
