The Rust community has experienced some turbulence in response to the
cancellation of a keynote talk at the upcoming RustConf event. The
Rust project leadership has now put out a blog post
apologizing for and explaining its role in the event, describing its
“decision-making and communication processes” as the primary cause
of the failure.

Organizationally, within leadership chat we will enforce a strict
consensus rule for all decision making, so that there is no longer
ambiguity of whether something is an individual opinion or a group
decision. We are going to launch the new governance council as soon
as possible. We’ll assist the remaining teams to select their
representatives in a timely manner, so that the new governance
council can start and the current leadership chat can disband.
