Clarification related to BDR

 I came across a link published in postgresql, where it is clearly mentioned BDR as an open source. When I tried to install BDR for CentOS from 2ndQuadrant, the yum repository was not reachable and upon further enquiring with 2ndQuadrant, I got a reply from them quoting as follows 

"BDR is not open source. We do not have plans to open source this."

 Can you please help me understand, why the following news is published in "postgresql" with an encouraging message acknowledging BDR as an open source? We invested time and effort to use BDR only to understand at a later point in time, that it is not. Kindly clarify, if I am missing anything.
