Why BSL classic?

Pattern HashiCorp + MariaDB: protect against hostile fork (Elasticsearch → OpenSearch story) while preserving trust. Auto-convert to Apache 2.0 after 4 years guarantees future OSS state. You can trust the protection isn't permanent.

The 4-year window aligns with typical SaaS market-formation cycles. After conversion, any party can fork, host, and compete on identical terms. MarvisX retains the head start of the project's core team during the formation window, then opens fully.
