Terrible analogy. I leave my house locked because I don’t want people to go in. On a website, I want people to read it, but without disturbing others. A better analogy would be that I open a small art gallery with free entrance and someone sends in an army that barely fits in the room.
Anubis is just a patch that shouldn’t be needed; it annoys regular visitors and prevents people on low-powered devices or with JavaScript disabled from reading the site at all.
