Well, that's a bit not nice. I took the "Rust is like C" line to mean is that you can use Rust anywhere you can use C, running at C speeds (the whole zero cost abstraction/no runtime/unsafe blocks), someone that can't be said about OCaml/F#/Haskell (TTBOMK). EDIT Moreover, if you look at context, you'll see that his point is that when it comes to OS design, a rust based OS will look mostly like a C based OS.
