I think you need to take a serious step back and actually view his work for what it is. You're acting like the guy deserves a Noble prize for his contributions to society.
I never mentioned any prizes. In fact, only one sentence of the above was a positive comment about Hans, and most of the the rest pointing out his flaws as a project leader.
But, prisoners generally are encouraged to work as part of their rehabilitation, and it seems to me that if his skills are most useful to the public in the development of software.
Nobody said he's Albert Einstein or Jimmy Carter. Just that he's done useful work for society--millions of people use ReiserFS, and he's worked for the US government for many years doing cryptographic and plugin-capable filesystem work--and that he could continue to do useful work for society with a few minor modifications to the terms of his imprisonment.
If you think Open Source software on the scale that Hans was involved in it has no value to society, then we'll have to agree to disagree.
