Just for independent verification purposes, I tried to find a free copy of this book using his search terms, and didn't come up with anything in a few minutes of clicking after results.

It appears that there is a 5th edition of his Javascript book and a 6th edition of another author's HTML book easily reachable from those terms, but no free electronic copy of a 6th edition Javascript book.

Google will remove links to pirated copies of books, one needs only submit a DMCA request. I doubt that DMCA requests will drive publicity for your book launch like an entitled blog post, though.

Not just that, but there seems to be no sixth edition available from anywhere at all, with the possible exception of a torrent that I didn't bother to look closer at.

Why are we talking about this issue at all?
