Re:We're switching to a DCO for source code contributions

You are both right. You can relicense MIT, assuming you follow certain requirements, including replicating the copyright notice, but you are not required to give away the source code (even just to the original artifact) at all. The user has to find its own way to the source code.
Replicating the copyright notice for attribution does not imply you are licensing it under MIT. You are following the original license requirements that permit your distribution.
On the contrary, it says that the copyright notice (= the license) shall be included in all copies (I assume, it's about derivative works as well).
From my understanding, one can throw in some non-MIT files or code pieces, but MIT code shall remain MIT-licensed until rewritten or removed.
Can you please point on where I'm wrong?
