Author here. Agree! The whole npm ecosystem is based around npm packages shipping JS files and doing anything else would break it. I've updated the article to hopefully make it less confusing. The takeaway should definitely not to only publish TS files to npm.

I mainly work with Deno which can run TS files natively (disclaimer: I'm employed by them). This changes the parameters a little as all registries for Deno could always ships the TS sources directly. But when publishing to npm you always have to publish the JS sources to work with runtimes like Node that don't support running TS natively.
