In any competitive environment, like game development, a tiny minority will win. I don't understand why that then gets drawn to "bundle sales aren't good for most...". I was never exposed to indie games until the Humble Bundle, for example.

Competition leaves a majority that does not win. This is true in capitalism, nature, sports, you name it. Whether that is a good or bad thing is separate, but I don't think it needs to be extrapolated to "bundles and Steam aren't good for most". Competition itself is not good for "most".
