Please, dear hacker friends, understand: This is the result of a blind adherence to a general policy of adding copyright notices to all programs. Not an absurdity of copyright law.
There are plenty of absurdities in copyright law. But I don’t think this stems from any of them.
This was an enjoyable light hearted coffee time read. To me there is a deep / fun question - can you copyright the absence of something? And apropos of true, there’s false, which has my favourite program description ever:
false: does nothing, unsuccessfully
That’s tshirt-ready right there.
