Facebook has insane growth, even today. It had double digit revenue growth for over a decade. For instance, in 2021, their revenue grew 35%, the year before, 20%. You'll see similar numbers if you look at their MAU and DAU. With that kind of growth over a decade, pretty much any valuation is cheap today. Sacrificing even a little growth for revenue today is a bad tradeoff because of compounding effects.
Similar growth in percentage terms (more actually as they're getting more efficient as they scale and have more user data). Pretty much all facebook numbers are up and to the right.
