This is direct warning to merchants, who offer low levels of service, to be ready to face a possible downgrade in rankings. A dip in rankings will affect sales, traffic and profitability of the online merchants. Simple as that
I'm sure it's a bit more complex than that. How is google to know who is good and who is bad.
Most reputable sites will not be sharing customer information with Google. So where are they going to get their information? ResellerRatings? bah .. that site can be gamed just like the others... the BBB ? bah .. as long as a company responds to bbb complaints they maintain their A+ rating.
So where will they get their data? Google Checkout? well ... maybe 1 out of 200 sales on our site are Google Checkout so that's not a good slice of data.
