The CI was somewhat minimal interpretation, that posits some sort of transition between the quantum realm and classical information during measurement, but says little about its nature. That left the field open for other interpretations to be more specific about collapse/​projection/​measurement, variously portraying it as objective, subjective, actually decoherence, etc.
So the collapse only exists in straw-Copenhagen? Or is it yet another scientific theory that popularly gets mistaken for Copenhagen interpretation?
