Cloudflare has some other features like a Web Application Firewall (WAF) and bot protection/filtering (which seems like it would solve their problems too?)

From the article:

> Presently, we use Cloudflare as our CDN or WAF, as it is a widely adopted solution.

To me, it sounds like the author isn't really familiar with the difference between a CDN and WAF is; or familiar with Cloudflare beyond it being a popular thing they should probably have for that matter.
