That was the remnants of windows phone. The people app would automatically sync all of their social accounts for a person.

As Microsoft moved more of those apps out of the inbox image and to the store, the functionality slowly stopped working.

The sunset of windows phone ended the rest of those features.

Yes but my feel (at the time, by the sources slowly dropping and degrading the functionality) it wasn't MS who slowly strangled that functionality. Do you have any articles on that? I'm really interested on what ecactly happened that time and considering the whole Nokia debacle...

Whatever Microsoft was doing, it's also the case that the social apps pulled back the APIs, as they wanted to own the feed views and push recommendations over chronological view. When Cambridge Analytica hit the news media, that was a nail in the coffin of open social APIs, but they were already dead.
