The problem with provider supplied services like hosting and email is that people understandably don't want to tie cloud services to their home internet connection. What if you move, or find a provider that offers better/cheaper internet service.

As a result, few people use them, and because they stopped being a competitive advantage, providers stopped offering them, and when they do, it is usually not free and a borderline scam. A way to add fees to unsuspecting users for something they won't even use.
