If I don't see the point of Elixir, or I don't like it, or I simply straight up hate it, why would I go into HN submissions about new Elixir versions and spew my personal opinion that has nothing to do with the topic at hand?

You can just skip commenting unless you have something actually useful to add. Even if it's criticism of the specific thing, but at the very least make it on topic instead of general digressions that just add noise to the conversation.
