The issue is probably touchy. It may not be possible to share "objective" facts with the public. This unfortunately makes it harder to differentiate it from FUD or another instance of open source drama.
The thread starts with a (vague) statement against Amazon trying to expand its control on the Rust project.
It later ends up being a spat between rust team members (who aren't a part of Amazon) on the role of the Core team.
I feel Steve does not have enough support among the members of the rust teams for whatever he was going for with this. The derailing of the discussion also makes it seem as if there are other issues at play.
Sadly, this may end up amounting to nothing more than burnt bridges.
