Google, a company who wants to do everything, really wants to be PayPal. Unlike some market leaders, eBay is willing to fight back in meaningful ways. Google tried throwing a Google Checkout Freedom Party during eBay's conference. eBay told Google they would pull all ads if they didn't back off, and Google backed off. Nice. See, eBay is a customer of Google. Some self-destructive industries have been learning that attacking their customers doesn't work out very well. Now Google's got a taste of it: you're in business because of your customers. Staying in business is easier if you remember that.
