The official derivatives of Ubuntu really are Ubuntu. If that makes you not want to use them, there's nothing wrong with that, but for other OS recommendations I'd suggest asking in a community that's not all about Ubuntu--our suggestions for non-Ubuntu OSes might lack some important insights. Furthermore, there are many OSes in the world, even many that are substantially similar to Ubuntu, so what you're looking for might be a broad discussion, rather than answers to a narrowly scoped question. With that said...
If you want to know which official derivatives of Ubuntu ship without software that automatically sends personal data to Canonical to search Amazon, that question can certainly be answered. The functionality you're trying to avoid is provided by the unity-lens-shopping
package. This is a Unity lens, and it is absent by default in derivatives that don't use Unity at all.
(Of course you can also simply uninstall that package and log out and back in, but I understand that's not the solution you're looking for.)
Ubuntu flavors not shipping with Unity (and thus also not with unity-lens-shoppping
) currently are:
I've listed these in the same order as they appear here, and excluded Unity-based flavors.
While I encourage you to seek other sources of information about other distributions, two distributions similar to Ubuntu are very popular: Debian, our upstream distro (i.e., Ubuntu is a derivative of Debian), and Linux Mint, a popular unofficial derivative of Ubuntu. (Linux Mint also offers a version based directly on Debian instead of Ubuntu.)
While they don't have huge user bases, I'd consider two unofficial derivatives of Ubuntu (besides Mint) to be particularly notable: Trisquel GNU/Linux, which includes only free software (the current stable version is based on Ubuntu 12.04); and Ubuntu MATE, which uses the MATE desktop and might get official status.
I understand this answer does not give everything you're looking for, and I reiterate the need to consult people and resources outside the Ubuntu community for a balanced picture of which OSes may be most appropriate for your needs. However, I think the question of which "Ubuntus" ship without Amazon search integration is of interest to many people; perhaps some of them will be helped.
To me, and many other users, this is clearly SPYWARE. The unwillingness to talk about the subject and closing questions related to it will only drive people away from Ubuntu.
