They are supposed to be readable still. If you can't then that's an accessibility issue, not censorship. Try turning up your screens contrast.

Comments get further and further greyed out as they are voted down more and more, to the point where they do become unreadable. I've manually opened dev-tools just to read comments before. This is not an accessibility issue, this is definitely a censorship issue. Why should an unpopular opinion get greyed out to the point it's unreadable?

I don't have accessibility issues and I don't make this up. I've seen comments with a text color of #eee, I had to go into the inspector to make it readable.. Maybe that has been changed/fixed already which would make my entire comment pointless indeed. Personally I think grey out text should not exceed about #ccc.

Interesting, because HN's CSS only goes as high as #ddd.

Also, you can use text selection via mouse or appropriate touch gesture in order to read even the lightest-colored comment.

If you use Firefox, something I made a while ago might be useful to you, I certainly wouldn't want to read HN without anymore: https://pastebin.com/8StFpps9

To make comments readable, only the lines from 86 to 106 are needed.

I'm actually fine with HN's system because I think most of us know how to get at text which appears unreadable. But this seems like a very fair & reasonable suggestion.
