The vast majority of those people contract out the (complicated) maintenance in keeping it secure and performant, or they get hacked and their site goes down, or they get ~no traffic so performance doesn't matter and neither does their choice of blog software.
Entire large businesses (WPEngine, for example) have been built upon the overhead costs from blog operators having to compensate for it being a bad app.
My close friend is one of the sysadmins for the WP instance mentioned in TFA. Pull back the curtain and it's pretty ugly and resource-intensive to run WP at scale; I've done it myself.
