Most people I know who really cared about music refused to shop on iTunes because it had a low bitrate and DRM. On the other hand most people I know who really care about games prefer Steam over DRM free because of the client advantages, social features, ease of use and lack of DRM that bothers them (SecuROM, limited activations, etc.)
Well most peoples I knew at that time who care about music didn't knew it was actually possible to buy music online legally somewhere else than on iTune nor that is was possible to load non-iTune music on their iPod and most peoples I know who really care about games play them on consoles.
More seriously iTune was extremely successful before they decided to get rid of DRMs, it was mostly a PR stunt (which for once was a good thing for customers), but I doubt it was really something the "needed" to do.
You can't yell at companies for doing what their consumers want. You can't pretend your minority fringe is more relevant.
Of course you can, why wouldn't you ? After all you are one of their customers too, if they do something you don't like then you perfectly have the right to tell them so, whenever you are in the huge majority or in a tiny winy the minority is totally irrelevant.
