It's certainly stable for now but it doesn't feel as stable as Google's, at least to me. The main FB product is in a slow decline and IG, though doing well, is under constant threat from the latest social media app du jour. The whole VR push could work out but right now it feels like a long shot and if I were working there I wouldn't be happy betting the farm on it. I mean the very fact that they are anticipating such a drastic pivot to their core business in the future should surely be a cause for some concern.
