IE 8 activity providers and the big sales pitch

Installing IE 8 really brings home the bundling prowess of Microsoft. How many Windows Live Spaces, Encarta and Hotmail users signed up due to some bundle from the Microsoft giant?

Folks, say a picture is worth a thousand words so here's my anti-bundle message from a Firefox guy. I'm not clear on what an "activity provider" is exactly in IE 8 (Techmeme, Adrian Kingsley-Hughes and gallery), but I'm pretty sure I don't need a Hotmail or Live Spaces account.
