I noticed that this extension was changing the affiliate tracking for every Amazon.com purchase. When I disabled the extension, the redirect to their "tag" went away. I can't believe Chrome would allow an extension to do this unknowingly to an end user.
Here's what I mean:
When I visit Amazon.com with an affiliate tag:
The uTorrent Chrome extension changes it to this (r601000010-20):
Anyways, I've gone ahead and disabled this extension. Instead of using their chrome extension, it may be wiser to just use their web interface: https://remote.utorrent.com/
Or better yet, stay away from torrent downloading.
UPDATE June 24, 2013
I just saw that Amazon update the terms and conditions of their associates program:
"7. Except as agreed between you and us in a separate written agreement referencing this Participation Requirement, you will not use any Content or Special Link, or otherwise link to the Amazon Site, on or in connection with:
a. any client-side software application (e.g., a browser plug-in, helper object, toolbar, extension, or component or any other application executable or installable by an end user) on any device, including computers, mobile phones, tablets, or other handheld devices;"
This is surely in response to uTorrent creating this chrome extension. I'm sure that they were making a killing on this. But I hate it when I get tricked into something, which was their intention.
