I disagree. Sometimes they don’t antecipate the use case that we users of their assets have in mind, which in my case it’s a very niche one I believe. I’m building (trying) a FOSS game and would be nice if I get approval to redistribute this asset, as it makes easy for contributors to build/compile the project. I don’t asking to sell or edit the asset. My point is if I can redistribute the asset in some reconignized licensing (e.g., Creative Commons), giving the authors proper credits.
I already achieved success with this approach previously and I think the author wouldn’t mind of me asking (please let me know otherwise, author).
