I only cited those articles as sources for PC revenue exceeding console revenue as an industry. Tear the commentary a new one to your gleeful heart's content. As an industry the money is there, which was my original point.
As for individual games, Arkham Knight sold over 250,000 copies on PC in the first 24 hours at $60 a piece according to SteamSpy. It would have sold even more if the issues hadn't been so severe, and even more as the year went on. Plus DLC sales. Ignoring that kind of money would be a horrendously stupid idea for any business, even if it isn't the lion's share of their profits.

Edit: Also GTAV made 1 Billion in revenue over 3 days. Not profit in one day. In any case, GTA V is a serious exception to the rule.
You might as well cite Titanic and claim that romantic dramas make more money than action blockbusters.
