It might not have been on par with Tyson-Holyfield, but this week’s public dust-up between Amazon and Google at the PFF Summit must have been fun to watch.

According to CNet, things got fun when an audience member suggested that Google’s deal to integrate its services with Sony Ericsson phones violates Google’s Net neutrality pledges. The deal lets Google’s search option appear faster than any rivals.

An attorney for eBay interjected and said he’d “like to hear” someone from Google explain this. (Loose translation: “Mel Gibson will have an easier time explaining his comments than you’ll have with this one.”)

“We’re not sure the wireless world is quite the same,” replied Google’s attorney in perfect legal-speak. “This may be where we part company with you guys.” (Loose translation: “And the horse you rode in on!”)

Given Google’s penchant for cutting deals to elbow out competitors, we’re not surprised that the harmonious veneer of “neutrality” is wearing away from the pro-regulation crowd.

In fairness to Google, it’s using the free market to create new consumer-friendly services. Too bad the company is pushing so hard to regulate away efforts by other companies to do the same thing.
