Just don't hypocritically declare that other people can't also do the same. That's the point here. The hypocrisy.
So no, going flair-only is explicitly to silence those of differing opinions.
Don't get me wrong, they are well within their rights to do so, it is _their_ subreddit, after all. However, if they're going to dance around and act like a bastion of free speech, maybe it's time for some introspection.

That's what the OP was referring to. If everyone is going to call out Parler for being a propaganda channel, then apply the same standards to Democratic Underground, r/politics, r/antifa, etc.
But sure call it propaganda if you wish. Perhaps it is. Many anarchists such as my self are well aware of the propaganda we proactively distribute on a daily basis.
What the ancestor is complaining about is that when the right wing does propaganda, it is not called propaganda, it is called free speech.
It hasn't been just the downvoting, but as the crowd is thinned, increasingly more bots inflate votes, and those who remain are more deeply steeped in their bias perhaps it will be mainly downvotes from here on out.
Maybe if everyone disagrees with something you say, it's not the rest of the world's fault?
Are you Principal Skinner going "Am I so out of touch? No, it is the children who are wrong."
Sounds good but what happens when a loud group bases their beliefs on alternative facts (and select only alternative facts that specifically support their belief)?
What is the basis for this belief?
However I think you are wrong in assuming HN has remained non-political. There is a lot of politics going on in most threads. While blatant partisan shoutouts are usually not voted to the top and remain at low impact. Participants regularly engage in heavy political discourse. This includes responsibility to security breaches, workers rights (especially those of tech workers; e.g. should remote working be encourage; is flexible vacation policy good actually), taxation policy (especially those around start-ups), housing policy, transportation policy, justification of international sanctions and their effects, etc.
And no, this isn't a troll; it's one of those reverse-name subreddits.
