In fact it turns out that 12.04 has some lens making queries to different services when I was searching stuff using the dash, and I didn't know about it.
I fixed it with: sudo apt-get remove unity-scope-musicstores unity-lens-video unity-lens-music
(I couldn't find how to disable it)
It's not like I agreed to this when I installed the system, because I upgraded from a previous version (and a previous version, etc), and that behaviour wasn't there.
I don't know how Canonical could advertise these changes, but in the Amazon lens case I think RMS did it right.
