I agree with Stewer. If it costs 40,000 man-hours to produce a product competitive with Poser, then you have to be the exclusive seller of the product to recover your costs, meaning you have to keep the code under your own control. So this would explain the big delay with Daz Studio. They may not have realized how much effort it would take and what kind of risk they would entail by distributing a free "base" version.
