Any time I read the words vulnerable and plugin I just assume WordPress is involved somehow. I'm convinced that the internet would be instantly more secure if the entire platform died off.

It would.

It also would be a lot less useful. A lot of content is published through WordPress.

I suspect an effective approach would be encouraging ways to make WP more secure, or publish a secure platform that can easily be transitioned from WP.

Wordpress dominates internet outside megacorps. There are a lot of security issues but there is a lot of utility too.
