I dealt with this line in some detail on the site many years ago - see the Roadmap!!
To recapitulate:
Firstly, there is nothing wrong with 13 e3, second, yes there are improvements, and third, I prefer another 13th move now.
I would say that this constitutes enough of a 'hint' to the original poster, actually.
How would it be possible, or at least practical, to constantly update all chess books as soon as a move hits a temporary obstacle after publication? I don't think there would be many people holding the view that this should happen free of charge. Often books are out of date in some lines between completion by author and publication.
I'm sure the original poster is well aware of this and therefore I'm wasting time stating the obvious, but other than an occasional generous online update from Quality Chess I can't recall many publishers/authors offering ongoing maintenance for free. Chess Stars, for example, published three versions of the excellent QGA book by Sakaev/Semkov - not many purchasers of the first book would expect free updates in the form of the second and third editions.
Authors need to make a living and buying their books or paying for Chesspub access is a way to help them do this.
As for Tony's book being 'a waste of money' based on your perception of one particular move (which Tony believes is actually still playable) I think that's nonsense. I have the book and have learnt a lot from it. If I were to read it more thoroughly I would still learn a lot more, too, despite it's date of publication.
