Well, there's a belief that it's locked. I maintain that's actually the big lie, and I say that for this reason: I get a PDF document, and if I can read it, if it is accessible, and there's a good chance it may be, I can take that document, turn it into Notepad or move it into the drafts folder of my email program, and immediately I can do anything I want with it.
In my opinion, the notion that a PDF document is automatically protected is a big lie.
As to why so much is just not produced, I guess there are those who see it as not a sufficient market. In terms of Braille, a lot of kids are now mainstreamed. Do itinerant teachers know Braille? Do they believe in Braille? There's an assumption that we read everything electronically now.
That's an unfortunate assumption, and it's an unfortunate idea, because as I said earlier, our road to literacy is Braille. I've learned so much about spelling and punctuation by having my fingers go over Braille. That's something you just do not get when you listen to a document, whether it's a book or a report, or whatever. Braille is so important, but it's just not given the priority it deserves.
