Clarification related to BDR

From

Hi,
 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.

This news is from 2016. At that time, BDR was open source, but it has since been closed.

BDR version 1 was Open Source, version 2 and 3 are not. Version 1 
(patched 9.4) and Version 2 (community PG 9.6) are not under support 
now, stable and supported version is 3 (PG 10 and 11, 12 soon).
You need a usage license which is bundled with a diamond support 
subscription.


Regards, Andreas

Santhosh,

2ndQuadrant has invested time and effort into the BDR project for the last 8 years and continues to do so.

BDR1 is open source and it continues to be available on 2ndQuadrant's GitHub: https://github.com/2ndQuadrant/bdr. This version, however, runs on PostgreSQL 9.4 which has now reached end-of-life. 2ndQuadrant, the developers of BDR, don't recommend using this version and also no longer support it, nor do we provide binaries.

The recommended version is BDR3, which has a new architecture and many new features. BDR3 has been developed under a different and more viable economic model which allows us to provide rapid response and hot fixes for high availability and security issues to users, as well as rapid development of new features. Many companies are now adopting this and new users are welcome.

We remain committed to the active contribution of major new features and timely bug fixes to open source PostgreSQL. We will continue to contribute features from BDR to open source PostgreSQL over time, subject to community acceptance.

In my opinion it is not a bright idea to not have support for any 
product. Support is an indemnity against blame game. If you face a 
catastrophic issue with the product and have no support team/company,
the blame will fall on you as you the person associated with the product.
