Besides that, even if it would, the books would not have been in the Public Domain. From the announcement:
> In Germany, they are copyrighted based on "life +70 years" of copyright protection (so, copyright will expire after 2020, 2025 and 2027, respectively).
From a legal and business perspective, neither German legislation nor the Fischer Verlag are at fault here. It's just the way it is (in Germany): Creators hold their intellectual property for life and can make sure, their heir profits from the work of the (grand)parents, as well (+70 years after death of copyright holder).
And while I understand, that Project Gutenberg has limited resources and may have no desire to do the extra work of blocking works on a case by case basis, it would not have been difficult. Instead, they have chosen to collectively punish all people from Germany, which resulted us to be seven years without access, at least as long we did not utilize a VPN.
I am very happy, that this has been resolved now. All the legal hassle has cost (non-profit) money and was worthless, because the solution is the same now, they could have implemented seven years ago.
