They do specifically mention this:

“No one owns CSV. It has no real specification (yes, I know about the controversial ex-post RFC 4180), just a set of rules everyone kinda agrees to respect implicitly. It is, and will forever remain, an open and free collective idea.”

They even seem to think it is a good thing. But I don't see how not having a bunch of implementations that can't agree on the specifics of a file/interchange format is a good thing. And being free and open is completely orthogonal. There are many proprietary formats that don't have a spec, and many open formats that do have a spec (like, say, json).

That's true of the vast majority of protocols that people use in real life to exchange date. We're using one of them right now, in fact.
