OpenOffice, the opensource (free) suite which is mentioned in Ebidloader as an alternative to Microsoft Excel, was taken over by Oracle, and then given to Apache in 2010.
The techies behind the OpenOffice open source started their own, LibreOffice, and now that is developing and leaving OpenOffice behind.
It is probably that point in time when those who use OpenOffice might consider switching to what is becoming the new default for opensource office software.
