> As if you can't program C# functional style.

This, I was really impressed recently when I met a C# dev who was also a programmer (as opposed to your standard C# SaaS dev who just copy pasted from the framework docs and stack overflow and was fully automated by Claude in 2025) and he showed me how nice the language has gotten since I last used it over a decade ago when it was just Microslop Java. They've really put in work and it has a lot of great functional constructs now.
