Apple is a publicly-traded company. Every, single decision they make - just like literally 100% of other publicly-traded companies - are with profits in mind. Period. Whether any of us agree with that approach is irrelevant - especially when we continue buying iPhones at record-setting rates.
At their core, I believe Apple is a company comprised of all walks of human who, in large part, likely have a concern for the state of our environment. It just so happens that taking that stance, or leveraging that angle in marketing collateral, is also good for business. So from Apple's perspective, removing charging bricks is a win-win.
That said, I do find it odd that they no longer offer a charging brick for a device that - on its own - requires a power brick for charging. The headphones was one thing. The brick seems weird. And that the cost of the brick wasn't passed down to the customer is why Apple is a multi trillion dollar company - again, right or wrong.
At the end of the day, the consumer speaks with their wallet. People can complain all they want. But as long as they continue buying iPhones, there is literally zero incentive for Apple to change anything. And why would they? if you don't agree with something, but continue buying said something, there is zero change anything will change. It's just math.
