They dropped a pretty beefy bombshell in the last paragraph that there were issues beyond accountability that they refuse to disclose. I'm absolutely certain that the core team has a good idea what they are talking about, the problem is this is a public letter, the intended audience is everyone, and they specifically attack the core team's credibility. When I resign from a job, I send my resignation to my employer in private. I wouldn't put anything in it that I'm not comfortable with becoming public, and if they wish to share what I wrote that's fine, but the purpose of being discreet is to leave the level of disclosure up to the other party's discretion. You don't send a company wide email saying "management knows what they did, don't believe a word they say, I'm out, peace!"
