> What am I to do?
Pick your priorities. There will never exist enough products to check all of the boxes that all of the people say is important to them. There is someone out there who would much rather have a product cost some amount less at the cost of accessibility features but they think a device that 'just works' is important so they buy the iPhone anyway.
The point is that your conclusion here is both the correct/obvious one, and that it ensures one explicitly cannot vote with their wallet. They have priorities too significant to be able to take part in the protest. They are invisible to the company they WANT to vote for.
The good thing about voting is that not everyone needs to be right. The average vote is always far more accurate than any individual vote.
