I sometimes see game assets or animation assets on a site that claims the assets are free and are under a #copyleft or even an #OSI-approved license. Yet when I try to download them, I need to have an account to download them. Then they're not free. The site owners can remove the asset or remove access to it, which doesn't make them free. If I can do what I want with that asset under the license, then I should be able to download them without an account. #GameAssets
