Many sample book titles have harsher DRM than the actual purchased title, a little conniving way to entice a sale. Use your frustration to make a case to the publishers against DRM, instead of blaming a single eBook product which isn't even the source of the problem. You probably know that this behaviour is only unique to eBooks where the publisher has disabled copying in the DRM settings. (Which isn't unique to iBooks.) So don't buy that particular book and make sure you let the publishers know why they lost a sale, if you have purchased it - request a refund from the store, you'll likely be granted one. Until then you're pissing in the wind.
