> Now you are arguing against closed-source, not liberal open source licenses. Non-copyleft licenses provide no protection against proprietary derivatives. If you have no objection to proprietary derivatives, then I think that's a weak stance to take. It means you don't care if your users can be given your software but without the rights that you intended them to have, because someone between you and your users can always take that right away. While your users might come back to you to get the same software with the same rights you intended them to have, they might not be aware of this, or they might not want your software alone, but together with whatever else was built on top of it, which they cannot get under your original permissive terms anymore.
