Why paid, and how long

LeastAction is a research effortat heart. The paid tier is what pays for the team to keep working on it. If the open-source + community model becomes self-sustaining, the enterprise features move to Apache 2.0 — not a promise for a specific date, just the direction we’re heading. We’d rather have the conversation about that honestly than pretend the paid tier is a permanent institution.
