If by better buying decisions you mean not apple then I've already taken some steps there. And it's not naivete it's dissatisfaction with not only the system but apple's choices as well. There are many ways to increase shareholder value and profits and we may find apple's choices were great in the shorter term for their shareholders but not so much over the long term for their customers.
For example, if anti-trust regulations hit them hard and cause dramatic changes to how they can run their business it may result in some significant losses that perhaps different choices could have averted. Maybe price increases helped set another record quarter but decreased customer satisfaction or retention that could have a more long term impact beyond the next quarter.
It's incredibly reductive to assume that whatever makes the most profit *right now* is necessarily the best move even for a public company.
Taking your money elsewhere is the best course of action in a consumer market.
Having said that, Apple's MO is what literally every other businesses out there is wishing for. I mean during 2020 and 2021, we have pandemic. Apple raised prices (iPad Air 4 and iPhone 12), unbundling chargers from iPhones, and yet they have record breaking quarters. Go figure.
So yeah, making the most profit is the best move for a public company. Note that Apple is not only profit maximizer, they're also master in marketing (eg. justifying removal of chargers as environmental move). So there's smart business play as well, but in the end, the goal is profit. And clearly it works for Apple.
