That is one of the risks involved with using proprietary software.

a few viable alternatives have been proposed previously in this thread.
In particular I would say, to summarize
- if you really need the GUI, but can give up on strict Matlab compatibility
Scilab + Xcos is the way to go
- if you don't really nedd the GUI, Octave can do with dynamic systems most
of the things taht Matlab can
I would also suggest giving a look at OpenModelica:
http://www.openmodelica.org/
which seems very promising, although the frequent references to "open source"
on the web site make me wonder whether that is really free software.

Fortunately it is not so :) most Octave developers are first of all Octave
USERS,
they are paid for the work they do WITH Octave not on Octave.
Some are (ore have been) paid to work on Octave.

part of this reward is that working cooperatively to improve Octave gives users
a better tool and makes them more productive in their everyday work.

The recommendation is very welcome and appreciated but unfortunately the
approach you suggest
does not fit with the way Octave (and many other free software projects) work
and cannot be implemented.
You seem to think of Octave as a company similar to the Mathworks, but it isn't.
Octave is developed by many indepent individuals who mostly develop those
extensions they need
for themselves (or that someone else pays them to implement) and then agree to
share their work with others.
One of the issues involved with selling Octave (or add-ons) would be how to
distribute the
revenue deriving from its sales among the many contributors.

I was trying to explain that Octave does not come at zero cost either, it is
a common mistake to confuse the term "free" in "free-software" with "gratis".

Oh, well. I don't think there is a way to actually "buy" Octave, the GPL
license
is especially designed to prevent anyone from taking away freedom from the
software.
On the other hand, Octave developers could be hired by a proprietary software
company, but, as Jordi
said, some would be reluctant to accept.
