The current decision of Ubanto's founding company, Canonical, of integrating desktop amazon searches by default, and the fact they send your queries to their own servers, for who knows what.
Still, even for people who don't like Ubuntu (I myself run a vanilla Debian distrib), I think it's still a good news because it might give an incentive for constructors to ensure their hardware is FOSS compliant.
In other words, Ubuntu can be another troyan horse for free software.
Again, I'm no expert in these things but that's how I see it anyway.
