I wish I could get a free copy of the updated electronic book if I own the outdated paperback 🤔 but I guess it’s against the overall business model 😄

Not at all, our official policy is that if you tweet a photo of yourself with the book and let us know about it, we will send you a code for free ebook. We announced it some time ago, but maybe we should make an announcement article about it to make it clear.

Of course, it is not a good deal for us, as we have very little from a paperback on Amazon, but we want those who bought this book to have access to it in other forms as well.
