In 2012, developers hacking LibreOffice code have been around 320, with a majority of volunteers and a minority of people paid by companies such as SUSE, RedHat and Canonical (plus a multitude of smaller organizations such as Lanedo, which is also a member of our Advisory Board and builds a significant part of its business by providing development related value added services on top of LibreOffice code).
The graphic visualization of the individual commits has the shape of a “long tail“. The pie is an explosion of the work done by the top 33 hackers with 100+ commits: 16 volunteers, and 17 paid developers (11 from SUSE, 5 from RedHat and one from Canonical). At TDF, we do not have “paid volunteers” because we love transparency and truth.
