"No politics" was an experiment that lasted less than a week. It was clearly labeled as an experiment at the time. I don't think that it's current HN policy.
Is the experiment really over when politically-adjacent threads are still getting flagbombed and removed? Just because it's not in the site guidelines doesn't mean it's not being actively enforced.

Yes; that was happening before the experiment, too. Most general political news has been officially OT on HN long before the experiment, and remains so under the general guidelines. The experiment was effectively a ban on that small subset of political content that would otherwise be generally within the guidelines.
OK, but you talked about "the day HN announced". That's different from user behavior. (And I'm not sure user behavior changed all that much. People flagged political threads before the short-lived official ban, too.)
