When I installed Ubuntu, the launcher included these icons:
- Search your computer and online sources
- LibreOffice Writer
- LibreOffice Calc
- LibreOffice Impress
- Ubuntu Software Center
- [size] Volume
(I'm not sure of the icons' official names, so I'm going by the mouse-over text. The Volume icon points to the NTFS volume on my machine, which is installed dual-boot.)
The odd one out in the list is "Amazon". I know that Canonical leads development of Ubuntu, and I am aware of the controversy about sending search results to Amazon by default (in an earlier version). I know Amazon offers Ubuntu installations on their cloud servers. But how did Amazon get an icon on the launcher? Did they pay Canonical money? Did they pay by donating a substantial amount of development to Ubuntu? Is it a left-over element of the deal that sent them search results? Some combination of those? Or something that no one knows except lawyers for Canonical and Amazon?
I did some web searching and found that there was an agreement to give Amazon the icon placement, but nothing about the terms of the deal. But the articles I found didn't say whether the terms were undisclosed, or if the terms are public but not just mentioned in the articles.
