alt Hacker NewsSome people always forget that GPL is about the end user's rights, not developer's rights. If a fortune 500 re-implements some GPL library to make proprietary, then by all means. It changes nothing for the GPL code, it's still GPL and its license should guaranty user's rights.
But a proprietary fork doesn't change anything for permissively-licenced projects either! The open original is still available, you can still use it and fork it. If it's a popular project, a community-maintained fork will always happen.
As a user, permissive licences give me enough freedom.
