I ran a highly trafficked adult website for 18 years. In the early days, CDNs were unattainable for me and I managed my own rudimentary network by hosting bare metal servers in data centres around the world, using geo-ip aware DNS servers to send traffic to the closest data centre to them.
My most significant running expense was bandwidth cost. So I never switched to cloud since the bandwidth costs would have instantly bankrupted me. Cloudflare, on the other hand, was the single most significant development when it came to my bottom line. Adding a basic, $200 / month business account saved me thousands per month on bandwidth + server costs.
DDoS protection was just a nice perk.
Most small websites are hosting with cloud providers these days. If their websites are at all media rich (and most are these days), and those assets can be cached by a CDN ... the cost savings on bandwidth are not marginal. They are often the difference between being able to afford to host your website or not having one at all.
There are, of course, ways to optimize and reduce those expenses without a 3rd party CDN. But if Cloudflare still has their free plans for smaller traffic volumes, it is often a financial decision to use them over your cloud provider's CDN options.
