It really doesn't. After all, many (most?) other languages like Java and JavaScript are implemented primarily in C and/or C++.

Where it gets deserved opprobrium is that it has no memory safety features, and thus inherently contributes to gobs of security vulnerabilities, and there are safer alternatives now, like Rust.

C is basically "portable assembly", and it's rarely the right tool for the job these days.

Can only patch so many buffer overflows, off-by-one errors, format string vulnerabilities, integer overflows, race conditions, use-after-free errors, etc, before it gets to be a bit tiring. Safer alternatives exist.
