I think this is one of the biggest points about communication: It requires both sides.

It doesn't matter if you have a clear and well-defined protocol for how you communicate if the other side can't, won't, or don't follow it.

It's like a web browser that only supports HTML. It may get the content your web server sends, but not the context and intent included in your CSS and JS.

And it's a lot easier to just say, "I only need the content, anyways."
