On the Amazon Associate discussion boards, the regulars are all people with web sites. If that's a representative sample, then those using PPC are a distinct minority.

I think you'll find a significant number who were doing PPC direct to Amazon but they generally don't participate in board discussions.

There are a lot of people using PPC for arbitrage purposes and Amazon was only one among a huge number of targets.

Anyone generating PPC traffic to their own sites and then linking to Amazon from there remain unaffected.

(Disclosure of my bias--I am an Amazon Associate with a website, and have never used PPC advertising, whether to my site or Amazon's)

Ditto myself.
