But the "practice" is not backed by a CLA or a code audit.  So what
exactly LO has is "license soup" as far as I am concerned.  I can't
touch it, though corporations that have no proprietary software
business may be unconcerned about such hygiene issues.  But I'd note
that such an approach will limit the project's success, since large
corporations, even if just using open source software, have their own
risk calculus to consider.   So the work we do on code pedigree audits
benefits not just the big bad software vendors. But it also benefits

to MPL.  I think there is or was some TDF misunderstanding about the possibility of "relicensing."
 As far as I know, only the owner of copyright has a choice about licensing.  E.g., Oracle
licensed the code base that was under its copyright to Apache in a different
way than it had licensed to others.  That's separate from the general but narrow availability
of that code under the LGPL from both Sun and Oracle.

forever). If a work is specifically multi-licensed, one can choose which one(s) to honor.
