Wasn’t it something more similar to “saying that you don’t care about privacy because you have nothing to hide is like saying that you don’t care about free speech because you have nothing to say”?

Both of these posts are complaining about their accounts being banned, which happened because they (at least one of them) posted low effort questions and therefore got lots of downvotes and got automatically banned by a system meant to ban bots and trolls. The irony is that reddit has major problems with their automatic moderation which you yourself as an user is completely powerless to controll, e.g. recently when a massive amount of nsfw subreddits were banned for being unmoderated which they later admitted was erroneous.
