There are quite a few businesses that don't feel the need to grow but instead focus on providing a consistent service and good employee benefits.

Keeping a website generally available 24/7 is usually pretty trivial of a cost compared to the costs for everything else in running a business so to me putting effort into limiting business hours seems unproductive. If you receive significant malicious traffic or attacks during off hours it may make sense but otherwise the cost of keeping the lights on for a server are usually marginal at most.
