Why is there proprietary code inside open source code in Pentaho Kettle 7.1 ?

Question asked by Yaoxing Li on Dec 1, 2017



I'm wondering why "PENTAHO CORPORATION PROPRIETARY AND CONFIDENTIAL ..." exists in some source code of Pentaho Kettle. It is Apache v2 licensed, isn't it ?


The propietary code I found:
