Those are just stories that made it to press and that I was able to dig up quickly. Durov did visit St Petersburg from time to time, it was an open secret when I lived there.
As for the last story: I was a bit sloppy about that link, the story I was referring to is better covered here [1] (that's a disgruntled employee spilling beans).
The fact that Telegram was still being developed in that Zinger building in St Petersburg was not particularly secret either, VK'S HR was not coy about the fact when showing me around the office. I also heard the same from multiple people working in that building.
