(1) The ransom model caps the amount that can be extracted from the
market.  This means that a blockbuster product will produce the
required revenue in a very short period of time.

In other words:

Ransom License[tm]: the more valuable the underlying product is, the
closer the approximation to free software becomes.

Hey, Adam, that looks like something you can use on your web page.

(2) The post-ransom free license can be copyleft.  Expiration of
copyright results in public domain, which is not copyleft.

               Ask not how you can "do" free software business;
              ask what your business can "do for" free software.
