We might argue it's influenced by FP indirectly because those adopted features from ML etc also jive well with functional programming, for example pattern matching as a control flow construct...
It's true it's arguable. But if we start calling the languages that adopt FPL pioneered features "heavily influenced by FP" we end up putting a lot of languages in that set, like Java, Python etc for having GC and closures. So in order to use that as a distinguishing feature I think it's warranted to make the distinction.
