> Is SQLite halfway to closed source software?

Is there a reason that you chose SQLite for your counterpoint? My hot take: I would say that SQLite is halfway to closed source software. Why? The unit tests are not open source. You need to pay to see them. As a result, it would be insanely hard to force SQLite in a sustainable, safe manner. Please don't read this opinion as disliking SQLite for their software or commercial strategy. In hindsight, it looks like real genius to resist substantial forks. One of the biggest "fork threats" to SQLite is the advent of LLMs that can (1) convert C code to a different langugage, like Rust, and (2) write unit tests. Still, a unit test suite for a database while likely contain thousands (or millions) of edge case SQL queries. These are still probably impossible to recreate, considering the 25 year history of bug fixing done by the SQLite team.
