You could read Guide's message (assuming the first comment is quoting it accurately) as being sarcastic about Tim Peters' banning. The mods probably feel like this is undermining their authoritah, and dropped the banhammer.

It reads to me as kind of petty sniping that's unlikely to really contribute anything useful to the conversation. But not something that really seems worth hiding either...

I guess it could be considered to breach the Code of Conduct, disrespecting the decision to ban Tim?

  Being respectful. We're respectful of others, their positions, their skills, their commitments, and their efforts.

This seems to be the perfect pretense to justify any sort of banning an organized majority would want.
