If you are a Facebook user, you might have seen the ability to get in touch with people who are in your address book from Gmail, Hotmail and Yahoo among others. Facebook, does have tie-ups with both Hotmail and Yahoo for importing and accessing Facebook data.
However, there is one service which does not offer it and it is Gmail, it is most likely because of the growing rivalry between these two, and it will now escalate thanks to a new change in Gmail’s Terms of usage.
According to TechCrunch, Google has now made it clear; not directly to Facebook though; in their terms of usage that anyone who makes use of Gmail data will have to reciprocate them in the same way or stop using them altogether. Here is what the new TOS says (emphasis added).
5.8. Google supports data portability. By accessing Content through the Contacts Data API or Portable Contacts API for use in your service or application, you are agreeing to enable your users to export their contacts data to other services or applications of their choice in a way that’s substantially as fast and easy as exporting such data from Google Contacts, subject to applicable laws.
On one hand Facebook has been ruthless with users, even a partially blind person who wrote a Firefox add-on to extract email addresses from Facebook to several other companies who have tried to access data on Facebook. And they have been easily using data from other websites for their own purposes, that’s definitely double standard.
