Also in a previous comment by the author, before the DMCA:

I also believe that it's not in Trello Inc. interest to try to censure us because of the Streisand effect, and it would be overly complex (I live in France, Yaşar lives in Turkey, we don't have a common company or an organization, and in fact we never met each other in the real life), and even if they stop us, and because the code is distributed under the MIT license some other will take the relay (remember PopCornTime anyone?).

That, combined the author posting it to on HN several hours after getting the DMCA, makes it clear that the author does not care about blatantly ripping off and redistributing others' work. Regardless of whatever their proposed solution would be for correcting the infringement, I doubt this project will ever be safe to use under assumption of an open source license.
