Self-serving? Yes, this post by Simba Hosting is a bit predictable for a firm that sells backup software, but it deserves a wider read. Statistics are not readily available, but it seems a reasonable assumption that most WordPress sites are small and have comparatively little traffic. They may also have relatively weak defenses against attacks. Most likely rely upon hosting companies to patch or notify them of needed updates for WordPress, MySQL or PHP. As the Simba author notes, "WordPress runs around a quarter of all web sites on the internet," and the motivation is money.
A recommended read.
