This is very true. A lot of corpsites of SaaS and similar companies run wordpress - i think because it's easy to find a "web developer" who can build very impressive custom themes that you wouldn't even know are blogs. My last company was paying about $500 a month to various "Professional Wordpress Hosting" companies to host their .com -- and they all had spotty downtime records because they were serving everything dynamically. My strategy to fix these has always been to install a "static site generation" plugin, stick the wordpress instance itself on a cheap host behind an IP restriction, and have the site generator plugin publish the site (on every change, which is never even that often) to some static hosting (S3, etc). Saves 99% of the cost and makes the site 50x faster and able to handle infinite traffic. But most companies don't seem to do this, and individual blogs are even less likely to.
