I've never been tempted to go back and buy old games because there's just too much new crap in my backlog already, but IF I were a current customer of GoG, I'd be pissed, and if I was considering becoming a customer, this'd be the deciding move for me.
Yeah, it generated a lot of news, a lot of publicity, but it has fostered so much distrust and shown a real lack of judgment. Dangling customers' spent money in front of them and hinting that it may be lost is about as smart as Michael Jackson dangling that baby off the hotel balcony.
