I'm happy to accept that C sucks (it does) and that Rust and others are superior (they are). But if you stop at the quoted statement, you've not said much. I upvoted the submission blindly, then read it, then un-upvoted it. TFA is not useful. It would have been better to not write TFA at all. There already are many many very good articles about how Rust is better than C.
(And Rust is not really any better than C in this regard. At least, in a vacuum. I guess you could make the argument that it's better because fewer people have false beliefs about it, but that's not an argument I'm making, either in the blog post nor here.)
As far as I know Rust doesn't claim to be, or have legions of people claiming it is.
That's quite common take on C though, which is not that wrong, if you go back in history far enough. It's quite wrong today though.
