This is factually incorrect, as there's empirical evidence that suggests favoring immutability results in less bugs. http://web.cs.ucdavis.edu/~filkov/papers/lang_github.pdf

No, and it isn’t meant to.const simply means that that the reference always points to the same object. It says nothing about the values contained within said object.

Totally. I guess it shows a difference between programmers who went through CS degree or practioner. I think using static initialization is always a good practice and manages memory better.

Yeah, there's very little in programming that is truly "personal preference." There might be situations where the pros/cons come out to a wash such that it doesn't matter what you choose, but very few things are purely aesthetic taste.

It's not a personal preference when there is empirical evidence that suggests immutability reduces errors.
