Search is bad at finding what you want but good at keeping you searching.
Here in Canada, kijiji(ebay classifieds) was popular and has accounts and ratings. People still have moved to marketplace.
By practically any measure all of the things you've listed have been wildly successful.
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.
The moment they couldn't do either they got their clock cleaned (tiktok)
Lots of people don't want to sell ads, particularly not with a side of societal harm, even if it would be lucrative. There are other things to value.
