Nah that’s pretty clever, a little Easter egg

If I’m taking a screenshot, it’s because I want to accurately preserve what I’m seeing. Doing anything, clever or not, to alter that is a breach of trust.

Doing it for the purpose of branding/advertising, of all things, only adds insult to injury.

Tries it.

so I don’t expect it to be patched by Apple any time soon

Why would they patch it? It’s working as expected.
