A couple of years ago uTorrent started installing adware with their software as well, and everyone either bailed or went back to v2.2.1. So why would anyone be using the most current version of uTorrent anyway?
Laziness, in my case. I've just upgraded with each new version, no crapware has been installed and the ads... I don't spend any time in the uTorrent UI, I don't understand how they make money. I launch torrents and is gone, occasionally I check if something done but it's just open -> scoll list -> yes, launch file or no, oh well. I literally can't remember any product or service they've had an advertisement for. Before that I used Azureus Vuze, but it turned into such a horrible mess. I'm sure there's other alternatives but I haven't seen any reason to bother.
