Ok. It was so uncommon that I didn't encounter it for the 15 years preceding AWS. It's like pointing to a car that runs on vegetable oil. Yes there are IN FACT cars that run on vegetable oil, but nobody does it statistically. This is much different than the chance that a business (with income) is renting commercial space. Yes your local mom and pop pool company doesn't rent an office (and that's a non-trivial amount of businesses, as I've worked for some), but they aren't going to rent space in WeWork anyway.
