Notice they say Google may stop it for the "Google for Domain Names program".
But then they mention Oversee.net in the article. Oversee.net doesn't even use the Google for Domain Names program from what I hear/know. They use the Google for Search feed, and well - that doesn't evaluate domain names on an individual basis at all - once again, from my knowledge.
So even if Google does stop it, it doesn't even stop it half way on their own network, let alone the entire industry where we have Yahoo, MSN, Ask, Kanoodle, Looksmart, Miva, 7Search, and the list is HUGE...
