The answer is (most likely) Microsoft, I kid you not. I've worked with F# professionally for many years is its incredible how they are literally sitting atop a gold mine that is the output of Microsoft research and do basically nothing with it. Even though it's sold as an ecosystem, .NET revolves around C# and its related tooling.

"Type Providers" are an example of such negligence btw, it's something from the early 2010's that never got popular even though some of its ideas (Typed SQL that can generate compile-time errors) are getting traction now in other ecosystems (like Rust's SQLx).

My team used SQL Providers in a actual production system, combined with Fable (to leverage F# on the front end) and people always commented how our demos had literally 0 bugs, maybe it was too productive for our own good.
