Arko kind of did address it in his most recent blog post. He claims he was doing what was in Ruby Central's best interest.
Unfortunately for him he basically admitted to a crime because it came after he was terminated. He tried appealing to community and whatnot but anyone who's ever worked for a corporation knows that once you're terminated, it doesn't matter if HR forgot to take away your credentials or not, you simply don't attempt to access anything ever again. Having keys to something doesn't make you the owner.
