I assume you mean they are unchanged since they were formerly
licensed by Sun/Oracle as LGPLv3.

Who/What is "LibreOffice contributors" and what copyrightable expression
did they create in 2012?

Assuming you just made that up, please understand that it is illegal
under US copyright law (Sec 506(c)) to claim copyright for something
on which you do not actually own copyright.  That is why the ASF
stopped adding ASF copyrights to individual files years ago -- we
usually don't own the copyright to individual files, only to the
collective work, and instead hold non-exclusive licenses from the
copyright owners.

I am not aware of the copyright owners ever licensing the code as
MPL2.  It's a fine license, but you can't just decide that for them.
You would need their permission to do so, just like we needed
permission to change it to the Apache License.

If you want to add a comment at the beginning of every file that
just directs people to your project, you can do that without changing
the licensing.  However, I doubt that would be useful.  Just create
your own README and user documentation -- people don't look to the
code for information on how to contribute.

I suggest you just leave each file's headers as they are until
changes are made that you don't want to submit to the ASF (that's
fine, we only accept voluntary contributions).  If you make bug
fixes, please do submit them to the ASF -- they usually aren't
separately copyrightable anyway.

When you do make a change to a file, you can either add a comment
around or near the changed part to say that you changed it (and
apply whatever license you want specifically to those changes) or
you can change the header in a factual way that includes a pointer
to the license and the NOTICE file.  For example,

"Portions of this file are licensed by the Apache Software Foundation
under the Apache License 2.0 (http://www.apache.org/licenses/LICENSE-2.0).

regarding copyright ownership."
