Because this is not a dispute resolution mailing list, as it once was. The dispute resolution mailing lists - are now closed-source.
I've been on this list for years, I don't remember it ever being a DR list.
It is a general purpose list to discuss any matter regarding the English Wikipedia, including dispute resolution. About the only thing that will get you in real trouble is trying to discuss the content of an article, which get a "to the talk page" response.
