Somewhat agreed, maven is a build tool and packages it downloads do not execute code through maven. This does not preclude malicious typosquatting packages making it into applications built using it, but does provide some option for reducing the attack surface.

In practice I think most developers would be running their project on the same exact box as they use for building it, which nullifies the separation of build/runtime environment. The reason that we don't typically see egregious typosquatting in the Java ecosystem is that Sonatype has a manual check on the claimed namespace for the organization publishing a project (among other checks). npm, Inc. could do this, but they so far have chosen not to.
