Michael Arrington says the spat between Google and Facebook over the banning of Google’s Friend Connect is purely and simply about control of users and user information.

“Internet giants know that the days of getting you to spend all of your time inside their walled gardens are over,” he writes.

“So the next best thing is to at least maintain as much data about the user as possible, and make sure they identify with your brand while they are out there not being on your site.”

OpenID is becoming popular with developers as it allows users to log into sites with IDs taken from elsewhere – thus encouraging users not to move all their info wholesale.

Facebook and MySpace, he says, keep users happy and prevent them from moving all their personal info to other sites by allowing some portability so they don’t leave entirely.

“Not too portable, mind you.”
