Well-written piece and it was exactly my takeaway from the whole thing. I was very surprised to find ANG had been hit with this. Not least because, as you point out yourself, "Jessica's Plight" was a much more obvious target.
Thanks. Valve must have used a script that looked for certain keywords in the game's description/title, I see no other reason why ANG would've been flagged for removal like this.
A bit frustrating that Valve hasn't responded to my email yet.
