The comment was not meant to be a threat but a statement of fact--you are welcome to participate or not.
Our rules, in fact, are entirely based on community feedback. Before implementing them, we had multiple discussions on what the users of the magazine wanted to see. We will also be reviewing the rules at a later date, so that people can share feedback on what they have liked and what they would like to see changed. However, we've had rules for something like two weeks at this point, so it's a little soon for that. You would be perfectly welcome to create a meta discussion on the topic. If one of the rules turns out to need addressing promptly, I'm sure we can do so, and that will also be based on community feedback.
Finally, no, we don't ban people just because they get angry about something and/or ask to be banned.
