I mean, no. This is hyperbole at best and just wrong at median. A system of relative trust has worked very well for a very long time - Linus doesn’t have root access to all our systems, even if we don’t have to read every line of code.
Npm on the other hand is much, much worse. Anyone can publish anything they want, and they can point to any random source code repository claiming that this is the source. If we look at how often vulnerable packages are discovered in eg. npm, I'd argue that the current level of trust and quality aren't sustainable, partly due to the potentially huge number of direct and transitive dependencies a project may have.
Unless you start to review the actual component you have no way to verify this, and unlike the Linux kernel there is no promise that anyone has ever reviewed the package you download. You can of course add free tools such as the OWASP Dependency Check, but these will typically lag a bit behind as they rely on published vulnerabilities. Other tools such as the Sonatype Nexus platform is more proactive, but can be expensive.
For npm, trust isn't really a concept. The repository is just a channel used to publish packages, they don't accept any responsibility for anything published, which is fair considering they allow anyone to publish for free. There are no mechanisms in npm that can help you verify the origin of a package and point to a publicly available source code repository or that ensures that the account owner was actually the person who published the package.
Security and trust is very hard, but my point here is that npm does nothing to facilitate either, making it very difficult for the average developer to be aware of any issues. The one tool you get with npm is...not really working the way it was supposed to.[2]

Maven on the other hand define several requirements, such as all files in a package being signed, more metadata and they also provide free tools the developers can use to improve the quality of a package.
If <random maintainer> commits code to their repo, pushes it to npm, and you pull that in to your project (possibly as an indirect dependency), what controls are in place to ensure that that code is not malicious? As far as I can tell, there are none. So how is this not trusting that <random maintainer> with commit-to-prod privileges?
Different risk profiles exist. There’s a difference between installing whatever from wherever, installing a relatively well known project but with only one or two Actually Trusted maintainers, and installing a high profile well maintained project with corporate backing.
This is true in Linux land, and it’s true in npm land. You can’t just add whatever repo and apt get to your hearts content. Or, you know, you also can, depending on your tolerance for risk.
For example (taking one of the top results for "javascript dependency management" at random): https://webdesign.tutsplus.com/tutorials/a-guide-to-dependen... talks about all the dependency management methods available. The word "risk" is not in that article. There is no paragraph saying "be aware that none of these package managers audit any of the packages they serve, and you are at risk of supply-chain attack if you import a dependency using any of them".
This doesn't get any better as you get more expert. I've had conversations with JS devs who've been professionally coding for years, and none of them are aware of it (or if they are, treat it as a serious threat). You can see the same in the comments here.
If there's not even any discussion of risk, and no efforts to manage it, then it's not really a relevant factor. No-one is considering the risk of importing dependencies, so the 0-100 scale is permanently stuck on 100.
