eobanb writes "The Yahoo-owned photo sharing site Flickr has come under fire recently for the perceived 'lock-in' that their API creates. Flickr's terms of service state clearly that all photos uploaded to Flickr by users are owned by their respective users, yet Flickr's API only allows uploading, not exporting. Surprisingly, Flickr developer Stewart Butterfield posted in the thread on Flickr: "I actually had a change of heart and was convinced by Eric's position that we definitely should approve requests from direct competitors as long as they do the same. That means (a) that they need to have a full and complete API and (b) be willing to give us access." This means that users will soon be able to freely move data between different photo-sharing sites, like Zooomr (which has already implemented the Flickr API), Google PicasaWeb, 23hq, or Tabblo."
