It didn't say that in the interview, but there used to be a ton of whining about it on various message boards. I never played the game online since Warcraft III put me off online multiplayer so admittedly I can't say whether this was the exact procedure used, but the infamous "zerg" rushing of winning the game in the span of a few minutes was widespread judging by the amount of vitriol it spawned on the boards.
I know there was one game where selling your starter buildings to rush was involved, but I can't say 100% for sure it was Generals.
