That's not the impression I have, especially given the "clarification" posts from X-Oz. Does someone know the legal reasoning of this? Would the same hold if you appended "You may not wear a hat on Fridays" which I think is closer to the BSD wording?

The 3rd clause of the 3 clause BSD license.

That says "may not be used to endorse or promote products derived from this software" while the X-Oz one says "shall not be used in advertising or otherwise to promote the sale, use or other dealings in this Software". There's the difference in verb, which I think is substantial, and I think X-Oz has added sufficient lawyerbombs to make me a lot more uncomfortable with it than the 3 clause BSD one.

I suspect we also have more postitive clarifications about the BSD one. It is possible we will get a bizarre interpretation from a particular licensor, but we'll deal with that when it happens.

I made a case elsewhere that
the X wording is actually less restrictive because it only affects the
original software, where the BSD clause affects all derived software.

Do both affect derived software, because we need copyright permission for the original in order to use the derived, which would otherwise infringe copyright of the original?
