Also, taking casual shots at HN rules or moderation isn't so much contrarian or anti-censorship as being disrespectful of the community and its expectations - downvotes shouldn't be surprising in such a case.
I merely pointed at the irony of the situation and said the quiet part out loud, effectively calling the hypocrites out :)
But yeah, it is censorship.
I have had multiple instances where my account was flagged because I expressed a contrarian view, and I couldn't actually participate because I was rate-limited.
No censorship also does not mean "genuine", 4chan is an example of this; virtually everything sans CSAM is "allowed", but genuine discussions are not happening because of trolls.
Ultimately, you will most likely not have a genuine discussion online, and irl you need a particular group of people who are capable of entertaining differing opinions.
In the span it took me to write this comment, GP received -3 and two other comments -4 total, proving the point.
I tried to respond to sibling chain, and to none's surprise, I have been rate-limited again and I am effectively banned from discussing anything in this thread :).
Communities become echo chambers as malicious means are used to crush opinions that dissent from the pushed narrative. Who wants to engage in a hostile environment? Most don't and will simply isolate or try to find another community.
