http://ubuntuforums.org – Ubuntu now contains advertisements from Amazon.com. If you make a search for music in your computer, the search results can include advertisements to buy music from Amazon.com. The feature can be removed by removing the package "unity-lens-shopping". Quote: It is no secret that for each product sold (not searched) from Amazon or the Ubuntu One Music Store, Canonical takes a small cut. http://www.jonobacon.org/2012/09/23/on- ... rovements/ What do you think about this?
