Code of conduct as a tool for humiliating

The Python community CoC (code of conduct), as far as that goes is pretty short and well written and doesn't really impose undue pressure on people. I would probably add a sentence about being forgiving about mistakes and assuming good faith.

I don't know the nationality of the original author, of course in an English speaking community it will usually have a Western European bend to it (to put it broadly).

I would read the article more as a cautionary tale about the limitations of text-only, asynchronous communication.
