As a non fanboy there might be one of numerous legitimate reasons for going to a pay to play format. They may be unable to support development without money, or maybe they want to be able to live somewhere other then mother's basement, or possibly, just maybe, they've finally gotten to a point where they feel justified in asking for some money to be able to play the game fully. I don't get why people are mad, these guys have put a lot of effort into the game from the sounds of it so why not pay some cash if you enjoyed it? Other niche games have done similiar if I recall correctly, so it's not like this is a new thing where a free game went pay to play.
