By the way, my stance on libre culture is this:
I am opposed to non-libre culture. As such, I refuse to make any of my work
non-libre. I once turned down an offer to write a book on Python programming
because of this principle and the publisher's unwillingness to make the book
available under a libre culture license.
However, I don't think it's productive to refuse to take part in a culture
composed of non-libre works. For example, refuse to watch movies that are
non-libre, or refuse to play games with non-libre cultural components. This
is just self-censorship, and it can alienate you from society. If you are not
a part of the culture, how can you possibly hope to end the problems it has
(such as being composed of non-libre works)? As such, there are multiple
games I play, multiple TV series I watch, and multiple things I read that are
non-libre culture, and I sometimes even promote such works. I may refuse to
support the publishers if there's an alternative, though (not the authors;
it's the publishers which typically restrict the distribution of works).
