This implies that charging bricks are potentially hackable. Pretty sure I don’t like that 😬

This is a good thing. In the past, updates happened on the assembly line so you were just stuck with whatever mistake was made for the version you had.
I disagree: When it was hardcoded, the motivation was to get it right the first time or face the consequences of a costly recall. Now, just send it out in beta! We can push a fix whenever. Or... Just never fix it, unless enough people complain.

You can disagree but that's literally how things happened (and still happen). Look at any single piece of hardware out there and you'll see version numbers. This is what they are.

Everything in this day and age has some kind of firmware to run it. Even your microwave and blender. Technically it’s all hackable, to some degree.

I wouldn’t lose sleep over it.
