I think there's a measure of success in thought leadership and/or product.

Apple is wildly successful at both, arguably more so the leadership than the actual product. Amazon, despite its faults, has a ton of businesses many of which do well, and it continues to innovate. I'm biased but I think Google is also in that category, with many new products that are widely well regarded (yes some were acquisitions, but typically smaller ones).

Meta on the other hand... Facebook was huge, no doubt. Instagram too, but that was already semi locked in on acquisition, they already had product/market fit at least. WhatsApp has languished under Zuckerberg, having had their explosive growth independently.

Oculus? Nope. Metaverse? Nope. Crypto? Nope. AI? Nope, or at least not yet.

By business metrics, very successful. By innovation in ads, very successful. But building new consumer businesses? Not really.
