You can add to the pile and even simpler than the redirect… HTTP ETAG [1], the company [2] being super happy to announce it:

    Today, Affiliate Window is happy to announce 
    the introduction of Flash Cookies and HTTP 
    ETag technology that will enhance our current 
    tracking solution. 

I don't have enough palms for my face.
It reminds me about the message [3] from Mark Watson from Netflix on this list recently 

    Sure. Democratically arrived at public policy 
    is certainly a form of user choice in this 
    context. Sometimes, though, people also want 
    to grant W3C decisions that status …

The thing is why the user should be the one paying the cost of bad practices done by other companies. Why should the user be more identifiable across the board to solve issues created by some rogue companies. The "good" companies should clean up their business maybe and become champions for the users, not the opposite.
