Imagine there was a universal standard shoe sizing system. But
Nike had their own goofy sizing method that didn't align with any other brand and made it difficult to convert and understand between them and everyone else. And then they were pressured to adopt the universal system.
And
Nike buyers got mad at this.
That's what Apple Fanboys sound like.
They don't want integration with what every other company does. They want proprietary phones and accessories that are overpriced 30-50% compared to market because then they can be "in the club" and take pride in being price gouged.
