Quote - I suspect that one explaination for why this happens is that the default choice is wrong (it's set as "Licensed for commercial use").
Having the default as "Not licensed for commercial use" would be much more sensible.

Yeah, but having the default as "Not licensed for commercial use" would be in direct opposition to the overall theme here.
(Subtly implying something similar which IS approved for commercial use is just around the corner, at a Marketplace near you)

But... words like "don't", "no", "forbidden" and their like tend to be viewed in a negative light - not something you want on your Poser Wal-Mart site.

Kill them all and let God sort it out, caveat emptor, and all that, but by all means, don't project to the public anything but happy happy joy joy, here is your free stuff.... ;-)

Plus, we all have seen time and time again here, whenever there are one of two obvious choices, Renderosity invariably chooses the one which will alienate the most. ;-)
