One might argue that YouTube and Android should go in that list, but I disagree. YouTube was acquired and it never managed to become something really big (it failed to compete with Netflix for video streaming, with Spotify for music and with TikTok for social network). Android also, was acquired and without a pletora of hardware vendor supporting it, it would have failed too (I'd say that Android without Samsung is nothing -- of course, it's big on embedded things, like cars or TVs, but it's not a world-wide product like gmail).
And likewise it is failing in AI, against OpenAI, which looks like another engineering-first product.
