I don't question Notch's intentions, but realize that Minecraft has been mostly influenced by the ideas that we contribute to it as a play-testing community from Survival Test to Beta. I think that with Notch taking cues from us and others in the Minecraft community, even a say from one person deserves to be heard.
By the way, if changing an icon wasn't heresy to others, including myself, we wouldn't be having this discussion, or this poll.
