Its ironic that the thing that is hard to learn about F# is C#, or more to the point, the patterns/idioms in C# libraries and frameworks. I've seen the same reaction more from people coming from other ecosystems personally working with F#. There's a lot of stuff in C# that people in Java/C# land take for granted that you just don't have to learn in other languages (Javascript, Go, Python, etc) - lots of OOP patterns, frameworks, etc. Staying in the F# lane seems to be easier but can be limiting, but at least you know you won't be stuck if you need an SDK/Library/etc.

The flipside is that adopting F# is less risky as a result - if there isn't a library or you are stuck you can always bridge to these .NET libraries. Its similar I think with other shared runtime languages (e.g. Scala, Kotlin, Clojure, etc). You do need to understand the ecosystem as a whole at some point and how it structures things.
