The reference doesn’t make complete sense in-context, either, as even if we presume Iron Fist takes place after the events of Captain America: Civil War, Spider-Man isn’t known to have made many public appearances just yet.
In the meantime, keep dreaming that Spider-Man might team up with The Defenders.
We’ve reached out to Marvel and Netflix to clarify why this change was made, and will update with any comment.
It’s plausible the bit was intended as an easter egg, but could just as easily be ascribed to error, or translation troubles with “Daredevil.”
