I don't know if you can really say that for a social network or a search engine. They naturally grew due to their network effects. A weird analogy would be saying "US should have no business growing to 300M if it has XM people under poverty level". Sure it should strive to do better, but doesn't mean that number can reach to 0. Sorry i couldn't think of anything else close to a billion users with systemic problems that's not a bigcorp so had to use government.
