It's clear over the last 6-months that the project lacks clear and mature (in multiple senses) governance. I suggest you quickly take the following actions:
1. The individual(s) responsible for this situation publicly apologize, With their name(s) attached, and possibly resign from their leadership position. This muddy, cloak and dagger, he said she said, stuff is completely unnecessary and just breeds distrust. The community/project needs clarity and accountability if it is going to survive.
2. All statements need to have names of individuals attached, either "John Smith, on behalf of Rust Leadership chat" or a big list of all members of the leadership chat. Stop hiding behind amorphous groups.
3. Adopt and implement the Leadership Council RFC. It's obvious this intrum leadership chat is ineffective in providing direction and clarity on the project. Rust needs a clear organizational structure.
