They have also seen a 78% increase in stock price over the past year so maybe using Facebook shareholders as an example isn't the best way to make your point
Yet in the long term I'm not so sure. Facebook's revenue is built on doing things that cannibalize the value of their platform-- annoying ads, creepy surveillance, even creeper "experiments" on their users, etc. That's making them decidedly uncool. Network effects are holding their popularity high for now, but while network effects are powerful they are not unstoppable. Things can "tilt" at any time.
I think that's why Facebook is acquiring things like Oculus. If they're to become the next Yahoo they want to make sure they've invested in some other properties. That of course is why there's still a Yahoo-- the core Yahoo brand is almost worthless.
