If oh-my-fish properly included the copyright and permission notice of the MIT license, then they are within the bounds of the license. It doesn't matter what the author's requests are, they can use it if they attribute properly. But they failed to do so and the creator's copyright was not credited, so they are in violation of MIT, which is pretty lame considering how easy it is to use MIT code in a compliant way. I am afraid this DMCA is legit.
