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).
Why not have a click-through at install or on version upgrades that says something like "we want to install an easy way to add products to your search results for which we get payment: Allow, Deny" ... rather than default install something that is going to cause such negative press.
IFF then there is a wide-scale uptake then there is warrant for auto-install of those features.
There are no ads. But if you use Ubuntu to search for stuff, and it searches for stuff and shows you the results, then some people seem to want to call those results "ads" where they represent products that you'd need to pay for to obtain.
