Your conclusion is reasonable, as long as "never" has the same
semantics as "Real Soon Now."

The incentive for the proprietary people, some of who are disaffected
employees, is the same as for anyone else:  it's more fun than other
things they could do with their free time.  Unfortunately, they
probably are legally prevented by NDAs of one sort or another.

The CAD _users_ face a much less debilitating obstacle.  They simply
don't know how to ... yet.  :-)  With open source, it only takes one
hobbyist.

And the tools get better every day, so the dividing line between the
programmers and the rest keeps moving.
