Mark Zuckerberg said that Facebook employees were blocked from finding friends with the Vine video app and blocked access on the day the service was launched. According to a document released today by the British Parliament, Justin Osofsky on Facebook suggested the day the App appeared on the iPhone OS on January 24.
"Twitter has launched Vine today, so you can create multiple short video segments into one six-second video," Osofsky said. "If someone does not object, we will stop accessing their friends API today."
Zuckerberg follows the document "Yes, go."
I speculated that it was part of the ongoing disagreement between Facebook and Twitter because it blocked Facebook's ability to find friends for recently acquired Instagram apps. Twitter eventually fell behind in alternatives like Snapchat and closed the vine in late 2016.
Osofsky says he has "reacted to PR" on Facebook's Facebook decision to block Vine's API access. You can refer to the Facebook blog post by Osofsky on January 25, "Make Our Platform Policy Clear". The post did not mention Vine, but "there are far fewer applications that use Facebook to replicate our capabilities or bootstrap growth so as not to create value for Facebook people." "Creating personalized, social experiences , Which allows them to easily share what they are doing in your app with people on Facebook ".
This exchange is the Congressional Digital, Cultural, Media and Sports Committee. It was originally included in a court document sealed for a US lawsuit between Missing app developer Six4Three who created an app for finding bikini photos on Facebook and Facebook. The commission seized Facebook's protest last month, but the content was not disclosed for the first time. Exchange via Vine was included as an example of competitors attacking Facebook by denying access to certain services in a well documented way at the time.
