Am I just blind or where the heck are those ads on Ubuntu? I use it exclusively all day and I just cannot find ads anywhere (other than on websites in the browser, but that's not Ubuntu's fault).

Not so hard, isn't it?
IFF then there is a wide-scale uptake then there is warrant for auto-install of those features.
