Yeh, maybe it's justified

The "race to the bottom" was started long ago when Sun allowed third parties to license the OOo code under non-copyleft terms. The intention of licensing any new LibreOffice code under the MPL was to allow organisations who had taken that route to transition to using LibreOffice as the base for their products instead of whatever ancient revision of OOo they'd licensed from Sun (and thus bringing them back into the ecosystem). This had nothing to do with Apache.

Indeed, it is precisely because LibreOffice made such a huge concession to the likes of IBM in relicensing much more permissively that there was so such disdain for Oracle's contriving to donate the openoffice.org trademark and domain names to Apache, where they would be jealously withheld from the living codebase.
