This would be a lot easier to jibe with if the paper was based on proof alone. A lot of the work in this realm isn't that. Plenty of these researchers are also fine engineers and I'm sure have great code. It just seems crazy to develop a new technique so completely and stop short of releasing the code.

I think it's because the academic culture encourages this as if the code detracts from the purity of the research.

I see where you're coming from. I think the truth is actually dependent on the particular institution and particular academic.

For example, OpenRave is the result of academics open sourcing their research.

Update: Someone posted a link to the code.
