No, they've only said that "something happened". That could mean as little as "one person did something". What they're accusing the rest of the core team of is not being a part of it, nor even necessarily of explicitly condoning it -- just of not explicitly doing, or allowing the moderation team to do, something about it. That may be bad enough, but IMO nowhere near as "dramatic" as "assert[ing] that they're all bad people".
