SO has been a truly amazing resource, but the questioners and answerers both were never more than resources for the company behind it to make money.
Stop acting as if you're surprised they're...doing things that will make them money. If it bothers you sufficiently, figure out a way to fix that problem. It's not like SO is some perfect resource, god, it's awful if you're a beginner. It celebrates a culture of being an asshole just because you can.
