like when you copy/paste from an article, only to discover the text includes a plug for the website…

It won’t actually get displayed with a “paste”, it’ll stay hidden to a human but be visible to the third party program.

Technically a solution, and if it wasn’t possible to just retype the words, it would actually be effective.

But if it can be defeated by someone manually retyping it, then it’s pointless. And that seems to be what their press release dances around.
