Some money was (voluntarily) contributed to my research program at UC Berkeley, and some even went to grad students as personal income. (in spite of my not asking for any money). I think the prospects for my making some constructive comments here are non-zero, even if I'm argumentative. There is a tendency for people doing Sage or sympy to be unaware of the previous efforts in the field, and to therefore repeat the design errors that have been mentioned in the open literature. So you are free to ignore my advice, write programs that reproduce the design flaws of Mathematica, Maxima, Maple, ... I have no problem if you give them away, especially with a BSD style license.
