I do. But I put both into the "cloud offering off-prem for very much money" shoebox. I setup a CDN once using VPS from different hosting providers for under 100 USD a month, which I would vastly prefer over trusting anything cloud.

And yes, I know that there's sites that need the scale of an operation like Cloudflare or AWS. But 99.9(...)% of pages don't, and people should start realizing that.

People who don't need that, also don't care much for an hour or two of service disruption. Most users will have far worse disruptions with the alternatives.
