Let's take an example:
Copyright (C) 2014, User A
other license (not MIT) in which people who
fork won't require mention of the current copyright notice
Copyright (C) 2014, User B & User A
Copyright (C) 2014 User C
(No link with User A because User B's license did not require mention)
Copyright (C) 2014, User A.
User B forks the project (with a new name) and his new own license. 1st question: What does he need to write ?
Copyright (C) 2014, User A and User B?
Copyright (C) 2014, User B (original author: User A)?
Moreover, let's say User B's license (not MIT) doesn't contain
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.anymore (this was present in User A's MIT license).
User C forks User B's project. As User B's new license does not contain the previous sentence (
The above copyright...), then User C has no link with User A's license. Is that right ?
2nd question : Is it mandatory for User C to mention User A?
It seems that in that story, User A's wish (his copyright notice to be included in forks) is not respected.
