I have open sourced all work I legally can for the past 20 years, and it has only given me more exposure and made it easier for people to trust me with significant budget to solve their hardest problems.

Also I happily buy lots of books from people like Cory Doctorow and nostarchpress -because- their books are public and I want to support authors that value the freedom of their readers.

Books that are DRM or copyright protected however, I buy used paper copies or pirate because why would I financially support people that do not respect my freedom?
