If you haven’t totally banned purchases from Sony due to the rootkits, you can at least now buy Sony BMG music tracks via the iTunes store; they’ve backed-down on refusing to have their artists available there.
Meanwhile Apple is under fire for including a “phone home” feature that’s turned on by default in the latest version of iTunes (the Mac version only so far?).
Update Friday 7am: EFF: Apple backs down on the “phone home” feature.
I turned it off straight away. More or less because I found it annoying.
