So people have their book already
And mine hasn't even been shipped yet, which means I'll probably get it several days late, maybe more than a week.
But the big point is: People already have the book, are already spilling the beans.
So the only reason for not making this PDF available to the rest of us as soon as it is ready has gone.
Now, it makes sense to make it available soon, as this will mean that people aren't treated even more unfairly than they have to be due to the facts that cannot be changed any more.
Not doing it is torture.
