Libre Office "even" supports the Open Office document format?

The Open Document Format IS both the Libre Office AND Open Office primary / native document format, and both programs should support Microsoft Office formats equally well.

The Open Document Format is NOT just a Libre Office or Open Office format, it is the most prominent global open standard for these kind of documents.

In 2010 Sun was bought by Oracle and since Sun owned Open Office Oracle now had control. As expected Oracle's early moves were not appreciated by the open source community and Libre Office was forked (in other words Open Office was dumped).

In a move that certainly surprised me (I don't know if I'm the only one), Oracle donated Open Office to Apache Foundation in 2011. This move seems to have rescued Open Office from oblivion.

Now we have both Open Office and Libre Office, both originally the same, and I presume, unless someone can clarify, they are now both still fundamentally the same but presumably with growing differences.
