Well, imvho I tend to prefer opensource software like LOover closed source softwares like ms office and kingsoft. Open-source projects are more transparent, and are less vulnerable to the kind of NSA/government hacking recently exposed. Not that day to day wordprocessing is an issue for the NSA, but I do feel that open-source is somehow more ethical. I've worded that really badly, but I hope you get my drift!
Just to muddy the waters....LO is better, simply because the majority of developers went over from OO to LO when it 'forked'. Result is that LO is being very actively developed and updated with features OO lacks.
I used to use OpenOffice. I've just got a new computer and had my old one formatted due to an infection. I asked the computer mending people to put Open Office on them but they've done LibreOffice as well. They seem to have strong feelings about what software people should be using
Have they done this for a good reason? Will switching from OpenOffice to LibreOffice make my life better?
