>Commits to Rust's master branch must be done through pull requests on Github. All PRs must be approved and reviewed before being merged, and the approver cannot be the same person who submitted the PR.

Any company that puts half an effort into open washing will follow these same procedures, so they aren't safe indicators that the real decisions aren't made behind closed doors ahead of time.

Paying close attention to things like the rfc process and approval process for commit rights and whatnot usually tell the real story.
