> Please cite ANY evidence that Amazon had anything to do with this particular EU packaging nightmare
Easy. Amazon spends several million every year to have their representatives discussing issues that affect them like that. We know for certain that they were indeed involved in the discussions, because that's what they are being paid to do (and it's not entirely objectionable for legislators to listen to industrial interests in the first place).

It may be incomprehensible to you, but like it or not these bureaucracy are what shape the modern world. Countries without an extensive bureaucracies are all failed state (and the first thing any emerging state actors, like the Taliban or HTS in Syria, do when they come to power is to set up a bureaucracy).
