I initially defended this Unity Dash adware with the same comparison, but after reading more about it, the Mint advertising is nowhere near as bad. All LOCAL searches are transmitted UNENCRYPTED back to Canonical! If users aren't aware of this new "addition", they will be leaking potentially private local information all over the net - I'm surprised this is even legal (it probably isn't in the EU). There is also no filtering done on pictures of suggestions returned from Amazon, so even pornographic images can be displayed - I guess this automatically bars Ubuntu from any workplaces/net cafes/universities etc. due to possibilities of dismissals, sexual harassment lawsuits etc.
