There appears to be a recent shift on HackerNews no longer support freedom of speech. I don't know that its just HackerNews either - it seems like its 'internet residents no longer support freedom of speech.' I'm not sure how to interpret this.
Internet residents aren't government. They can't arrest people, lock anyone up, or sentence anyone to death for anything, let alone for saying something. There's nothing there for speech to be free from.
Internet residents can, quite successfully, remove people from the internet and silence their speech on the internet.
Consider Kiwifarms. I am purposefully NOT going to talk about if something is deserved or not. I am not touching that one again. I am tired of it. That said, internet outrage of a minority led to misinformation (both for and against it) and ultimately resulted in the DDOS protection vendor no longer protecting it. Once that was done, to noones surprise, someone ddos'ed it and removed the ability of others to see it.
Its not that internet residents are trying to stop from hearing certain things - in some cases, they are purposefully stopping anyone else from hearing certain things also.
I don't know that I believe this fully but it seems, some days, the internet itself is a country.
