This is a real shame. I love DuckDB, and we've adopted/extended it and ducklake very heavily at Krea for our research.
I know the projects will remain open, and ostensibly still contributed to in the same direction, but surely AWS thinks of this as another piece of a product suite to compete with Databricks.
Nontheless, I think the open embedded query engine approach DuckDB is spearheading is larger than one project, and I remain excited about the broader ecosystem (especially datafusion).
