It was clear that Google had turned to the dark side when Eric Schmidt first spoke at the Search Engine Strategies conference in 2006. Until then, SEO was the enemy. Google and Yahoo had previously sponsored a conference in 2005 on squashing search engine spam. What's new is that Google has now managed to alienate ad-supported publishers, their paying customers, as well.
Huh? No, "ad-supported" means these publishers are getting paid to display these ads, not paying for anything, so they aren't customers. They're getting paid, which means they're suppliers. (What they supply is the eyeballs, yours and mine and everybody else's, that consume the ads.)
In business, "the customer" is the one who pays for a good or service they wish to acquire: Here, that's the advertisers.
