A quote from the documentation page you linked:
> With the default registry (registry.npmjs.org), unpublish is only allowed with versions published in the last 24 hours. If you are trying to unpublish a version published longer ago than that, contact support@npmjs.com.
Apparently, someone can remove established packages.
