YoY growth and quarterly earnings report don't give you a full picture of how much a company is liked (which is important for b2c companies like Facebook) and how well it is actually performing for the medium/long term.
GE and Boeing also had amazing YoY growth and great quarterly reports, until the underlying dumpster fire they were nurturing for years exploded in their faces and now they don't have growth nor profits anymore.
You could say the same thing about every big company. Apple has headwinds from sales in China and US-China trade wars, Tesla is trailing BYD and seeing declining EV demand, and so on. Every large company has something or the other going on. But I find it funny that every new project from Apple is reminiscent of iPhone 1 while it's the Yahoo path for everything from Meta.
