OP, OpenSearch, OpenTofu all seem to indicate the jury is still out on this one. I still see many smaller projects using open core. Three I started using recently ( llama-index, langfuse, qdrant ) are in this category.
There is certainly a difference between AGPL and BUSL style licenses. One of the new projects I'm using as some of their code with a BUSL style, but still open core primarily
Do you have suggestions for alternative funding/support models? What is open core being replaced by from your perspective?
