Seriously: stop it. It's none of your business what the author's license choice is. You don't know what the author is trying to accomplish by their choice of license. It could be a mindless choice, or it could be an informed choice. Perhaps the author wants to build interest and later plans to switch licenses (it's not like others are likely to fork _and_ do an excellent job of evolving and maintaining the fork). Perhaps the author is looking to get hired. Perhaps the author believes that BSD/MIT licensing is more free than the GPL. You really don't need to be shaming the author for not making the choice you made.
