Oracle Corporation continued developing OpenOffice.org and
StarOffice, which it renamed Oracle Open Office. In September 2010, the majority
 of outside OpenOffice.org developers left the project
 due to concerns over Sun's, and then Oracle's, management of the project,
 to form
The Document Foundation (TDF). TDF released the
LibreOffice in January 2011,
 which most
Linux distributions soon moved to,
Oracle Linux in 2012.
In April 2011 Oracle stopped development of OpenOffice.org
 and laid off the remaining development team.
 Its reasons for doing so were not disclosed; some speculate that it was due to the loss of mindshare with much of the community moving to LibreOffice
 while others suggest it was a commercial decision.
 In June 2011 Oracle contributed the OpenOffice.org trademarks
 and source code to the Apache Software Foundation, which Apache re-licensed under the
IBM, to whom Oracle had contractual obligations concerning the code, appears to have preferred that OpenOffice.org be spun out to the Apache Software Foundation above other options or being abandoned by Oracle.
 Additionally, in March 2012, in the context of donating
IBM Lotus Symphony to the Apache OpenOffice project, IBM expressed a preference for permissive licenses, such as the Apache license, over
 The developer pool for the Apache project was seeded by IBM employees,
 who, from project inception through to 2015, did the majority of the development.
The project was accepted to the
Apache Incubator on 13 June 2011,
 the Oracle code drop was imported on 29 August 2011,
 Apache OpenOffice 3.4 was released 8 May 2012
 and Apache OpenOffice graduated as a top-level Apache project on 18 October 2012.
IBM donated the
Lotus Symphony codebase to the Apache Software Foundation in 2012, and Symphony was deprecated in favour of Apache OpenOffice.
 Many features and bug fixes, including a reworked sidebar, were merged.
IAccessible2 screen reader support from Symphony was ported and included in the AOO 4.1 release
 (April 2014), although its first appearance in an open source software release was as part of LibreOffice 4.2 in January 2014.
 IBM ceased official participation by the release of AOO 4.1.1.
In September 2016, OpenOffice's project management committee chair Dennis Hamilton began a discussion of possibly discontinuing the project, after the Apache board had put them on monthly reporting due to the project's ongoing problems handling security issues.
