I just came across this article on ZDNet. When I read the title I just knew that most of the complaints would be about the installs. Sure enough, as I clicked through through the first 6 annoying applications the complaints were aimed squarely at installs that treat customers computers like it's ISV owned equipment.
It's a really good read and it's a good reminder why auto update patterns, unwanted bundled software, annoying reboots and ordering customers to widen the attack surface of their system just to use these applications is NOT Setup Goodness.
Unfortunately we are going to see even more of this garbage going forward as it's sadly bound to be getting easier for ISVs to hoist crap like Yahoo! Toolbar on users machines.
