I feel it's a bit of a tautology, the fact that they're resigning already clearly communicates there's an irreconcilable difference between the mod team and the core team. If the core team comes with an explanation that would make light of the situation surely the new mod team would be skeptical.

That said, there is still a bit of a game left to be played. The mod team just played their trump card, by instantly making the matter super public. But by keeping the specifics close to the chest they both keep their integrity and they give the next mod team some leverage for their interaction with the core team to resolve this situation.

It's really good btw that they're keeping the specifics private. Having someone publicly lynched is never a good situation, it's probably something that's offensive to a group of people, but the person(s) who caused offence probably have no bad intentions. It's hard running an organisation with a diverse group of people. You'll never get everyone to settle on the same moral values so it's inevitable that you'll get someone who is unapologetic about some value they hold.
