I mean, I took Sindre's move to ESM-only publishing as his own choice as the author and maintainer of his own OSS packages. In the spirit of OSS, he doesn't need to justify the choice, it's good enough that as the author he's making it. The previous CJS versions are still published, and anyone can fork the modules if they want to take on the maintenance burden of the CJS version.
That preference has had an impact on the Node ecosystem at large, given how prolific an OSS contributor Sindre is, but IMO that influence has been earned by the large body of work he's contributed.
