O-O was originally "Star Office" -- supported by Sun. When Sun was bought by Oracle, they forked Libre Office off, because the developers didn't want to deal with a proprietary system (like Oracle has done in the past with other things).
Also, O-O had gotten massively bloated by 2011. The Document Foundation folks went back and re-engineered the code to get rid of the bloat (when they came out with v3.5).
As it stands, Oracle dropped Open Office and it was picked up by Apache. I haven't messed with Open Office for a couple of years, but I read that the Apache team went and fixed O-O quite a bit since taking it over (but don't know that first hand).
Didn’t Star Office the proprietary version allow the user to create java (or something) animation very easily?
Which they obviously did not allow to go open source.
Which do you recommend? 4.0 is available, but I started downloading 3.41
I been doing software for near 40 years, and never cared for being on the bleeding edge...
