This isn't a good example - WordPress.com doesn't offer the same product as other WordPress hosts. With the latter, you're still getting "self-hosted" WordPress, but with the former, you're getting one install added to their giant multi-site installation (and all the limitations that that imposes).

That's not true actually, the software that powers wordpress.com is builtin and can power many sites from the same instance.

So while many hosters will offer a single instance (as it's more flexible), some, often companies doing it internally will use multisite just like wordpress.com.
