Reasoning: The text explicitly states that the package requires a commercial license from Sideway Inc. and cannot be used, copied, or distributed without acquiring such a license. This clearly indicates a commercial license, which should be labeled as "OTHER". The mention of previously open-source code does not change the current commercial status of the package.
