As far as I know, the BSD 3-clause and MIT licenses are functionally equivalent.
Can I take BSD/MIT-licensed code and use it in a project which I then release under CC0, the Unlicense, or similar?
(I don't have any particular projects in mind at the moment, this is more of a "could I do this if I wanted to" question.)
Update: According to this answer, you cannot, because of the notice requirement.
