They're not selling the library but a managed cloud runtime for a scaleout compute tier. The clientside library is part of the freemium, and as workloads need to go bigger, they want to be the easy button for that. That's similar to anyscale (ray), coiled & saturncloud (dask), and early databricks (spark). Managing infra for that kind of thing is annoying. These companies don't OSS their cloud stack. Wishing them luck! A lot of arrow-core compute tier & db co's emerging, so cool to see the many years paying off.
