If that's the best you can say about it, then Canonical failed.
Lately, I've been putting MINT on a few people's machines, and the love the "windows like" feel (necessary for the transition) and it's still based on Debian and very solid.
"I don't like Amazon lens about Ubuntu" -- Response from fellow Ubuntu user: "Yea, this sucks, I think I'm not going to use Ubuntu anymore"
I don't like Amazon lens either (there isn't even an Amazon.ro so it's mostly unusable for me), but they have to make money somehow.
Find another business model, this one sucks.
But think about this. Nearly everyone shops on Amazon. This is the easiest way to give money to support this OS. People all say "I'd pay for it" but that never works. Instead... going to buy something on Amazon? Use Unity, and support your OS. Dead simple, and you don't have to touch your wallet.
I actually want Canonical to be successful. I want them to be profitable and I wish they could find a way to make money without resorting to stupid gimmicks like this.

I buy things on Amazon twice a year (if that). I have a feeling I'm closer to the average PC user than not.
Also, the whole issue of inclusion of Amazon links could be solved with a single command, "sudo apt-get remove unity-lens-shopping".
And it's ridiculous that Canonical gets flak for trying out a new revenue stream (one that can easily be removed if its bothersome), while ChromeOS is championed (which essentially makes revenue off of your web usage, targeting ads, etc.)
If the community tried to be a little less abrasive and actually held reasonable level-headed discussions instead of being dismissive we could actually get somewhere.
Infact I'd argue that it's Canonical's leadership is helping since it has succeeded in bringing generally non-Linux businesses over to Ubuntu - Valve bringing over Steam, Spotify alpha, Rdio, etc.
