For my present math materials:
I do all the illustrations and typesetting myself. The book writing offer I got asked me to do it myself too. Note that I am a mathematician - lots of heavy duty formulas - our page arrangement can get to be really difficult (more difficult than biologists for example - my wife is one and I can compare). I do all the typesetting, indexing, bibliography, illustrations, and so do all my colleagues.
This semester I will be teaching by a free calculus textbook:

Mr Hartmann (the author of the book) has illustrations that are top-notch quality (he has interactive 3d graphics when viewed with adobe acrobat! That **beats** the quality the publishers can offer).
He did all the graphics and typesetting himself. Yes, he offers his LaTeX source code for free, on github, with a creative commons(!) non-commercial license.
If we get the math textbook publishing companies to go bankrupt, I will be one of the first people to wish good riddance of them (my reasons for being mad at them: exorbitant non-affordable prices combined with awful, deliberately low, quality of mathematics).

Conversion rate of 0.2%: so, sell 1million copies 10 USD each and get 20k income - a pretty good deal if you ask me. A top-notch author would sell a lot more than 1 million.

Donationware is not suited for everyone |
I agree. However I think one can similarly argue that copyright law is not suited for everyone. I would agree that copyright law makes some limited sense in entertainment literature, but in my opinion it makes zero sense for technical literature/manuals/textbooks, etc.
