Do you ever see job postings for C or C++ that only require you to know the language? Jobs are looking for domain specific skills, sometimes a framework implies such a domain like "React programmer"="frontend programmer", sometimes it's the other way around like "3d Effects programmer"="GLSL programmer". In all cases though, the bare language is never enough, no matter how many decades you used it, you have to have experience with special tools for your domain, be it frontend, graphics, operating systems, hardware or anything else. Why do you think this is distinct disadvantage to NPM specifically? You can steal someones account and do the same with Rust crate for example, or Go package or even C/C++ header only library. It can get installed or updated to malicious version on user side in the same way, because everyone uses version ranges like "^" or "~" or equivalent. And if you're going to say everyone uses lockfiles, NPM also uses lockfiles for many years already.
