Is there any point in complying with the licence which comes with a project published anonymously (like the initial Bitcoin source code)?
If so, in case of breaking the rules of your license, who has the right to enforce the aspects of a license if nobody takes the ownership of the project? So basically, can you do whatever you want?
"Can"
, yes, even if the author is known."Should"
is an entirely different beast. How do you want the world to see you?
