I feel npm gets held to an unreasonable standard. The fact is tons of beginners across the world publish packages to it. Some projects publish lots of packages to it that only make sense for those projects but are public anyway then you have the bulwark pa lager that most orgs use.
It is unfair to me that it’s always held as the “problematic registry”. When you have a single registry for the most popular language and arguably most used language in the world you’re gonna see massive volume of all kinds of packages, it doesn’t mean 90% of npm is useless
FWIW I find most pypi packages worthless and fairly low quality but no ones seems to want to bring that up all the time
