I sorta agree on the entire foam theory. If you don't like foam, the easiest choice is to ignore it. If you are afraid that the board will not sound as good as per what you expect without the foam, the easiest choice is to skip the board. if you really like how the board looks and can get over the foamless bad sound, buy it. The designer created the board with foam in mind and kept it optional, there is literally nothing wrong with that. I feel for a preference driven hobby, this is a stupid demand to force the designer in removing something that you could very well chose to ignore during the build.
