I'll open by admitting that I pirate games, music, and books. Plucking figures out of the air that I would suspect are accurate to about +/- 20% or so, I'd say I've purchased about 70% of the material I have pirated. Of this, I would have played, listened to or read close to none of it without the availability of the illegitimate sources.
Often I'll see something and think "hmmm, interesting, I wonder if it's any good", and there's no way of finding it out easily for me (worth while game demos, or good quantities of music previews are generally unavailable). So I use other sources to see if I consider it worth purchasing, and do so if I do, and delete it if I don't. No one is losing out here, as if those sources weren't available, I
still wouldn't be buying the material. I greatly value the ability to preview things in helping make my purchasing decisions. In some cases, such as the video game
"Humble Indie Bundle"s and Radiohead's "pay what you want" album, I've paid money simply to support independent creative development on principle, even when I'm not necessarily interested in the product itself.
Robert Jasiek's joseki book is an excellent example of when I haven't pirated something, because he's actually put some material up there for my perusal (and, as Amazon does this for books too, I very rarely have any reason to consider pirating books). I'd actually have preferred around twice as much material to be available so that I could more easily get a better feel for it, but the existing material Robert has put up has put it on my wishlist for some point when I return to the Go world properly.
I've been fairly active before in the PC Gaming piracy community (primarily involving rights and law discussions), and I very strongly suspect that this community represents more customers and sales for the PC Gaming market as a whole than those who have nothing to do with piracy. This isn't just anecdotal, it's supported by a fair amount of published literature:

This may or may not carry over to music or books (although from my personal experience I suspect it might for the former), but I think saying "pirates are bad, mmmk? If piracy wasn't possible, the book / game / music market would do better, mmmk?" benefits no-one, and simply polarises an argument that would benefit more from a mutual understanding of sides. Of course, some pirates will simply grab all they can get for free (particularly the younger ones, in my experience), but I don't believe anyone has a set of data complete enough to know whether digital availability has a net positive or negative effect on the artists' incomes.
I personally think the Go book market isn't very good because Go itself is a fundamentally very niche market. When I started OGS, I harboured vague hopes that I'd be able to make a fair amount of money running an online Go server, just like a number of people manage to do running online Chess servers. Ha-de-ha, how naive I was. The reality is, not many people play Go in the west, and even less regularly read Go books, particularly ones like John's.
Now, before I get hammered into the floor for undue criticism of John's literature, my statement wasn't intended as one. The depth, flavour, and background provided in John's books makes for absolutely riveting reading to someone with my preferences in Go, but we steadily live in a more and more instant society, and I can promise they'd sell much better if they were called "how to get really good at Go in 50 pages". He hits a niche part of the Go-book-buying market in a way that I don't believe any English Go author has before him, and I believe the Western community is a richer place because of it - I wish more people valued such contributions, as I think they are undeniably valuable, but the truth is only a minority of people play Go, and only a minority of those both enjoy the cultural and historical aspects of the game. Even then, I suspect only a subset of these have the money and willingness to spend money on deep and thorough Go books that are not likely to improve their actual skill at the game.
I also greatly enjoy philosophy, sociology, and theology. One author I enjoy is Bart D Ehrman, but how many people here have even heard of him, despite being a reasonably well known and respected author on the history of Christianity (from the precise semantics of language and the deliberate misinterpretations of texts over the centuries to the regional politics and power-mongering, he discusses in great depth theories of why and how Christianity has ended up in its current form)? Niche markets just don't make a lot of money sadly, regardless of the dedication, knowledge and wisdom of their primary protagonists.
I'll end by saying that you'll definitely be missed John. I have found almost every post you've written on here to be thoroughly worth reading all the way through (and, as some of them were pretty long, that says a lot on an online forum).
