I agree that that is what the word and phrase means, however in THIS context, it means something different. It doesn't ruin the idea if the idea is to share that it has easter eggs. If they didn't create, share and "ruin" it, they would have omitted an important feature (to put it in software terms) They don't want the reader to go and find it, they are overlaying ideas from the "Swiftie-verse" onto a tech platform and THAT is the fun part. It's just a little fun blog.
