Why wonder? The user who wrote it seems to be a pretty well established user, and their public repositories suggest that they work in adjacent contexts, so it's entirely plausible they attempted to use async-ip-rotator in one of their projects.
It's also worth noting that Feb 6 may very well be after Marko Elez became a public figure with DOGE. The article doesn't do a great job of expanding on any of this.

The public repos for this person that I could find that weren't forks with no activity to upstream consisted of a dice-rolling guessing game, rock-paper-scissors, and some kind of framework for downloading and transcribing audio files that does not yet download or transcribe, but implements a whole bunch of boilerplate. I find it rather difficult to believe this person engaged in a good-faith review of the async-ip-rotator code base.
