Two weeks ago a new version of the software was released but along with it came the silent change of license from GPLv2 to the "SQL-Ledger Open Source License" — presumably in an effort to prevent future forks like LedgerSMB. As it turns out, the author is making deliberate attempts to prevent the community from finding out about the license change. All posts to the SQL-Ledger mailing lists asking about the license change are being censored and direct questions to the author are going unanswered. This behaviour is not a first for this particular project, and is part of the reason for the original LedgerSMB fork.
So, does a project maintainer have an ethical obligation to notify his or her community of a license change? What about a legal obligation?"
