This is a ridiculous point of view. Those things are not mutually exclusive; you do not need to have complete proprietary lockdown to have a properly built quality battery.

Humans will lie and cheat for profit but at the same time humans also build locked batteries. It's just that nowadays we take away responsibility of people and their choices and we don't want to deal with the fact that when someone is buying a shitty poorly built copy, they are the ones at fault because of their greed.

You could very much have an open market (and should) it's just that people would rather believe there is nothing wrong when they buy something that is suspiciously cheaper than it should be.

Greedy corporations are at the origin of the problem precisely because they try to extract too much for their stuff, selling it at what is an unreasonable price.

You cannot at the same time blame people for their poor choices out of greed and at the same time re-enforce the same behavior in corporations, that's nuts.
