I can't remember who it was - maybe Stratechery - that theorized that Zuckerberg thanks to his experience running Facebook had a really good intuition for when Social media where going to go far and thus was able to make deals that at first looked wildly overpriced but in the end seemed to be a steal.

Perhaps their problem right now is that there hasn't been a social media with the growth potential that has been worth their acquiring.

At any rate not sure if I would say just because they failed one time (even with scandals of last few years) that they're really in trouble, that strikes me too much like most financial journalism that says oh no company X had a bad quarter that's it they're toast and then it turns out they come back the next quarter. I say that as someone who does not care for Facebook or any of their acquisitions (although lots in my family like Whatsapp)
