"Hey, we're selling your most personal data to Russian oligarchs and other shady people, who are using it to manipulate you and program your mind!"
"Still have cute cat videos?"
But critical mass has other applications - even for small businesses. On our little island, vistorship was down - way down - about ten years ago. As a result, none of the hotels or restaurants were making money. Many would shut down, halfway through the dinner hour, as there were no customers whatsoever. If you are going to serve things like raw oysters, you'd better be prepared to throw away a lot of oysters, or have a critical mass of people to support such a restaurant. Today, with new hotels and new homes being built - and vistorship up - we can support more restaurants, although it is still a challenge to get help (again, a critical mass of employable and skilled people need to be present!). But we are far better off than before - despite what the naysayers always say.
So, if you decide to open a business, ask yourself whether you have this critical mass of customers and employees, in order to make it work. Without either, you'll go broke. It is like the sad little shops that open up in Lansing, New York, trying to sell coffee or Nascar collectibles, or ice cream - without doing research first to see whether there is a clientele for these things. You can't just open up a cents shop and hope people come. It is a sure way to go broke.
