If the price is very low, is that close enough to "free"?

The extreme case that comes to mind is KCL.  You are not allowed to
use the product without a license, but you can get a license
(including source license) just for asking.  I would say that the
community at large has benefited substantially from this arrangement.
I use two products based on KCL--ACKL and OBJ, which are both
distributed under a similar agreement.

A less extreme case is Unix v.7.  Source licenses for this product
were available to universities for very little money.  The result was
a large (even though somewhat exclusive) productive community.

Problems have only come about today because the company that granted
those licenses has changed its attitude.

I would argue that cheap traditional source licenses can be almost as
good for the community as GPL-style licenses.
