This to me sounds like a misuse of DMCA - it's original open source code not stolen code, so the only "infringement" is dubious around whether you can clone a game or if a game belongs to whoever "owns" it. I can see they could have grounds to take the project to court to establish whether their copyright ownership of Wordle prevents anyone making their own version, but using DMCA for independently made code seems like a big overstep. Two corporations (Microsoft and the NYT) making decisions about whether software can be posted, and the poorly thought out DMCA rearing it's head again.
