After acquiring Sun in January 2010, Oracle Corporation continued developing OpenOffice.org and StarOffice, which it renamed Oracle Open Office,[42] though with a reduction in assigned developers.[43] Oracle's lack of activity on or visible commitment to OpenOffice.org had also been noted by industry observers.[44] In September 2010, the majority[45][46] of outside OpenOffice.org developers left the project,[47][48] due to concerns over Sun and then Oracle's management of the project[49][50][51] and Oracle's handling of its open source portfolio in general,[52] to form The Document Foundation (TDF). TDF released the fork LibreOffice in January 2011,[53] which most Linux distributions soon moved to.[54][55][56][57] In April 2011, Oracle stopped development of OpenOffice.org[17] and fired the remaining Star Division development team.[35][58] 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[59] while others suggest it was a commercial decision.[35]
