Author should be aware that Mojang has nuked copy projects before. Now that they have MS lawyers they will C&D anything that carries the "Minecraft" name relationship. Never even mention it, call it by more general technical terms like a "square voxel engine" or something.
If that had any ounce of truth clearly they would have tried taking down mineserver and minetest long ago.
If projects gets taken down it's because of copyright infringement, not because they are referencing the name. Removing all references to Minecraft won't do anything if the project contains assets or decompiled code from Minecraft either.
Minecraft is a trademark. You can't make references to it from your own work. Feel free to research mojangs history and intellectual property laws. You don't have rights, only privledges given temporarily by the corp. They can choose to C&D whenever they like.
You can totally reference a trademark without infringing on it, see Nominative Use / Nominative Fair Use[1]. Whether or not a usage falls under Nominative Use is ultimately up to a court to decide. Of course a company can send C&D letters whenever they like, that doesn't mean it's going to hold up in court.
With all that said I have never heard about Mojang or Microsoft sending C&D letters over someone giving their project a name vaguely referencing Minecraft. Do you actually have any examples, because when I google Mojang and C&D I only get examples of Mojang receiving C&D letters, not sending them.
