My name is Thomas, one of the original founders of cdnjs along with Ryan (linked below by another commenter).
We originally posted cdnjs on Hacker News in 2011 -> https://news.ycombinator.com/item?id=2828516
The project was originally created on AWS Cloudfront, Ryan and I thought we could handle the bills. In retrospect that was incredibly naive so we were fortunate to partner with Cloudflare.
At the time, cdnjs was a baby, Cloudflare had just started entering the market.
In short, Cloudflare always owned the domain, cdnjs.cloudflare.com, meaning, we were constrained to work under the DNS level.
We have both put considerable amounts of work into the project, but nothing compared to the community and the "core" contributors. I put "core" into quotes because for the last 5 years, cdnjs has largely been run by a highly dedicated man named Peter.

Peter built enormous amounts of infrastructure to support cdnjs. He is extremely diligent, intelligent and determined.
The project was Ryan's and I "baby" but we were happy to relinquish control, sorry for all the "buts", but we were not in a position to control due to the technical and commercial reasons.
Ryan and I have never personally profited off the project, we've only paid bills and late night ssh sessions.
Conversations are underway to move forward, it is likely that the project will move to an unpkg setup (assets are just mirrored to npm).
A lot to say, but I'm at a lack of words.
Happy to answer any and all questions.
