Let’s say I want to develop a public website and make it open source.
Can an open source license demand that derivative work keep a link to the original site in a prominent way?
On the one hand this shouldn’t look like a problem, as it seems similar to the widespreaad “leave credits clause in source code”. On the other hand, source code is not end-user-visible and such a demand to leave a link to the original site in prominent display means I am denying the freedom to modify that particular place of the software that causes the link to be displayed.

The question is not whether such a clause can exist (which I understand it can) but whether the license can still be called open-source with such a term.
