I've argued that for years. If "collapsedness" is property of a particle, then measuring one branch of a stream of entangled particles would modulate the collapsedness of the other branch and could be used for FLT communication. The bottom line is that nobody can tell the difference between a particle whose wave function collapsed and one that didn't. The conclusions from that is that wave function collapse is fiction. That video makes the same point in a more formal way.
