Yesterday, it was reported that people who wanted their photos off Google Street View had to provide a copy of photo ID and a sworn statement. There was also concern that there was no limit to how the info provided could be used. Now, they're backing off all of that and are confirming that the info will only be used for this process.

Methinks this is a sign that Google is listening to how its privacy practices are perceived and is taking action.
