Remember that free software licenses are irrevocable - even if a vendor changes a project to a non-free license, the older versions continue to exist as free software. So while we should absolutely criticise vendors who take the work of others and make it non-free, we should also bear in mind that they gifted us the earlier versions in the first place, and cannot take that away again.
