It's definitely fair to blame the book when the book gives advice that is impossible to follow.

If it's not possible to always give help and advice, sometimes you have to give an error message and unless the book mentions that then it is definitely fair to blame the book.

Eh, I read the book as presenting a maximalist vision: in a perfect world, all error messages would instead be help that lets you resolve your issue.

Since it says to hide error messages and instead provide help, anyone who hides error messages and doesn't provide help can't really be said to be following the book's advice. It feels wrong to me to blame the book for not, in every bit of advice it offers, saying "don't half-ass this incorrectly". That seems inherent to me.

It's not a very useful book if it doesn't provide advice that works in the real world. I have not read the book - does it give advice on what to do if it's not possible to give help? Or does it just assume that it's always possible to be perfect?
