Yes there’s products on CF that cost a lot of money. Like Argo. So… just don’t use that kind of product? All prices are clear. We are discussing the “free” CDN services. You will never get a random bill for that.
except the free tier? isn't that what people writing here about? never knowing when the free ride ends? up until now even the content type was not clear...
as other comments mentioned, CF is more like a "hey we noticed ..." kind of company and dont go around raising bills willy nilly, very different from AWS, etc.
