The basic idea of an antimeme is an idea that doesn't want to be spread or perpetuated. A secret is an example of an antimeme that actually exists, so I would say communication of the idea would also in principle be resisted. But creepy, wild sci-fi needs to go with 'what if that, but even more so?'. (though, I would also say a pure antimeme would be completely self-extinguishing. Actually the way these sci-fi antimemes work is closer to how e.g. real-life secret societies operate(d). There's a secret, and it is perpetuated within the group, but it's carefully guarded from widespread knowledge. The sci-fi idea is that the knowledge itself basically does this, somehow, to any entity not in the in-group, where the in-group is frequently non-human, maybe non-organic/non-sentient)
