It makes sense to use AWS/GCP offerings if you are already using many of their other services. Also it means you have a ton of cash to burn.
There are hundreds of thousands of companies that choose not to pay ridiculous price of AWS or not to use Amazon and Google at all - they use smaller providers, many of them manage their infrastructure themselves.
For them there is 0 reason to us CDN, DDoD protection etc from Google or Amazon. Cloudflare is one of the best choices for them. It makes sense even for AWS/Google clients that don't want to be changed millions for bandwidth like its gold or something.
