He’s known to include small Easter egg like references. Would those count as yes?

Examples:

• manifold app logo on iPhone homescreen

• Graph with “yes”, “no”, “%” buttons beneath it on a computer screen in the background

I don't have a strong intuition on what would better match the spirit of the question. Do other traders have an opinion on this?

Ok, this one will include easter eggs. I've made another market for the other interpretation.
