Facebook has not been hesitant to cut off data to applications that don’t share back, as Vine and Yandex discovered recently. Now it has blocked a photo app — Vintage Camera — with filters similar to Facebook’s Instagram, claiming that the app has received overwhelming negative feedback. But developer Presselite said negative feedback has been rare, and it feels that Facebook’s ownership of Instagram influenced its decision.
After Facebook revoked access to its data from Russian search engine Yandex’s Wonder iOS application last week, Yandex announced that it will pull Wonder from Apple’s App Store and put the social discovery app on hold.
In recent days, Facebook has been cutting off data access to applications that have been using it in ways that either compete with or replicate what the social network does — first with Voxer, then Wonder, and most recently Vine. Facebook Director of Platform Partnerships and Operations Justin Osofsky clarified his company’s stance with regard to sharing data. In essence, apps that allow users to share data back to Facebook are OK, while those that do not violate the site’s platform policy.
Add one more application to the list of those being blocked by Facebook: Vine, a new video-sharing app from Twitter, joined Russian search engine Yandex’s Wonder and voice-messaging app Voxer on the list of apps that have been denied access to the social network’s data during the past week.
Thursday, Russian search engine Yandex released a mobile application, Wonder, that was something like Facebook’s graph search mixed with Siri. From an iPhone or iPod Touch, someone could ask Wonder, “What sushi restaurants do my friends like in San Francisco?” and it would come up with a list, based on their Facebook friends’ likes and check-ins. A few hours after the app went live, Facebook pulled its data from Wonder.
The seventh-largest search engine in the world, Russia’s Yandex, is integrating Facebook notification data into search results.
