But if this expectation really were very common, what would be the harm of putting it in a licence?
replyMIT is simple, open, and common which is a big benefit for indie projects, small studios, and anyone with limited legal resources.
replyIt means there’s lots of info on the internet explaining how to use the license and they can be relatively certain they won’t accidentally fall into some legal trap or misinterpret the license. It also means there’s legal precedent around the license.
All that to say, custom licenses are actually a big issue for small players.
