What does it mean for Data Collector to be close source?

Currently, our source code is publicly available on Github under Apache Software License (ASLv2). Anyone may access the source code and if they choose to do so, compile it on their own and use it. 

As of Data Collector 4.0, we will no longer make our source code publicly available, and we will not be accepting community contributions to the code base. Our development team will no longer use the SDC Jira project, which is public, to track future 4.x Data Collector enhancements, although the SDC Jira will remain open. All 3.x and earlier versions of Data Collector will remain on Github, but 4.x will not be available. 

Cheers,

Dash
