SQL-Ledger Relicensed, Community Gagged
Yeah, the summary is heavy on the language, but the fact is that several community members tried to bring up on the mailing list the fact that the license was changed, but their posts were censored. I would say that meets your definition of Gagged. To date there have still been no posts allowed through to the list regarding the license change. The point now is mostly moot however, as the license has changed back to GPL so the remainder of the community will probably continue on never knowing what has transpired.
