You can't copyright short phrases and slogans like "bullshit-free".

I suspect it’s somewhat tongue in cheek. From the README:

> A "bullshit-free programming language" is of course a highly subjective opinion

I hardly think the author would believe the concept to be subjective and also believe they have a monopoly on the phrase’s usage.

Tongue-in-cheek, yes, but the concerning bit is "(c)" instead of "(TM)". If they don't understand the (huge) difference, do they understand the licensing of their code?

I read it as a strong statement that the author immediately cowered away from.

It's meant to be humorous™.

A surprising number of people don’t understand the difference between copyright and trademark.
