This is a failing of modern corporate culture. There is nothing wrong in reaching a stable equilibrium, becoming profitable, and if you are a public company, paying dividends.
It’s unfortunate that it’s become growth at all costs, there is something to be said about public companies just stabilising, and paying out profits to shareholders.
Now, that’s not to say Facebook is able to reach a stable equilibrium. I think they are struggling to maintain that, and that’s the problem. It’s a case of not loosing market share, especially when you have promised your shareholders the world.
