I agree with this - Cloudflare's pricing and function is clear here, and it seems perfectly reasonable and expected to have a cutoff size that they don't cache

I agree with this - Cloudflare's pricing and function is clear here, and it seems perfectly reasonable and expected to have a cutoff size that they don't cache at the edge. I get the OP was pissed about a big bill and felt like lashing out, but it's unfair to complain about Cloudflare when they've done nothing wrong.
