None of Cloudflare's marketing or technical documentation makes any explicit reference to "permitted usages" for Cloudflare services such as R2 and Workers.
This page for example means one thing without any reference to permitted usages and would mean something entirely different if the permitted usages were promoted with the same level of visibility as the benefits.

Nothing here tells me I cannot write my own video serving code with Workers:

You might even believe "whatever you need" from this paragraph from the above link:
"Static assets with dynamic power. Say goodbye to build steps which pre-generate thousands of assets in advance. Harness the unrivaled raw power of the edge to generate images, SVGs, PDFs, whatever you need, on the fly, and deliver them to users as quickly as a static asset."
This developer documentation would takes on an entirely new meaning if a link to "acceptable uses" was prominent at the top of each page (not fine print).

Have built an entire application around assuming there were no such limitations I now need to rebuild elsewhere.
Humph.
I now no longer even understand what "no egress fees" means - in a way that's worse than the big cloud providers where at least you know they are charging you 9 cents per gigabyte.
