Well, Joyent spun off Node as a separate org, and io.js's developers pretty much ran the dev side of the new Node.js org. So it really didn't disappear so much

Well, Joyent spun off Node as a separate org, and io.js's developers pretty much ran the dev side of the new Node.js org. So it really didn't disappear so much as replaced the upstream for the most part. I think a lot of Rust's governance and leadership has left some poor impressions in a lot of ways and the Trademark licensing is just the step too far for a lot of people. I don't think the goal is to necessarily destroy rust, but definitely change the direction somewhat dramatically.
