Probability is an illusion
Lack of effort... cute.
You have brought argumentation you claim is evidence, but is not any sort of evidence. Quantum mechanics follows laws and then there are also 6 postulates of quantum mechanics as well. Wave-particle duality represents that depending upon the experiment or measurement being employed, one or the other will show up, but this hardly subjective; furthermore there is causality and determinism within QM, but it is counter-intuitive to our experiences in classical physics, (the macro-world).
To very simply and accurately answer the question of subjectivity, if QM were not objective than the correspondence principle would not hold where small particles and forces give rise to what we see in macro-physics, but rather, we would see all sorts of non-sensical changes.
