After working in a corporate environment for many years, the one deciding factor in the survivability of text processing software appears to be whether the tool used was free open source or a closed source, binary only, commercial only product. Stuck with presentations and other documents in now unreadable or unconvertable formats, we need to look for ways to escape the trap of "closed" solutions as open solutions from the same era didn't suffer the same faith. We show how Open Source offers more than just "free software"; it offers better continuity and increased data preservation. If Darwinist evolution could be applied to software, open source software would be considered fitter and more likely to survive.
