He writes condescending articles that confuse and mislead newcomers to the language. From his redaction:
> In the previous version I trolled people by pointing out that, if what the Python project says is true and it would have been "impossible" to support Python 2, then they broke it and Python 3 is not turing complete. Obviously Python 3 is turing complete, but Python project members frequently claim something this basic is "impossible" soooooooooooo alright. I even had a note after the gag saying it was a gag, but everyone is too stupid to read that note even when they do elaborate responses to my writing.
