The original version of my post called out that you cannot actually see Cloudflare's pricing without an account, that link was the best I could find. Funny to be calling out their competitors for pricing when they won't even publish theirs...
Edit: I was quoting a 100MB per request limit but that's actually ingress, egress is 512MB/unlimited so if you calculate that out it would be an even smaller fraction of a penny per terabyte for bundled workers.
In this case is because they actually does not charge bandwidth. I have few services on CF and never paid a dime for bandwidth. Even on free plan I push few terabytes.
