Those 99.9% can go buy a phone. They don't need PinePhones.
What if the Raspberry Pi suddenly tried to be an everything computer for everyone? Now it needs a case, and a faster CPU, and expandable memory, and SSD, and a bigger power supply, and so on, until it's practically a NUC that costs $400.
Part of the success of the Raspberry Pi is that you can load whatever OS on it you want. Imagine if you could ONLY run Raspberry Pi OS!
That’s not the issue with the Pine64 ecosystem, though.
The direction they’ve chosen is actually similar to what Raspberry Pi has chosen: You can boot alternate OSes, but the primary focus is Raspberry Pi foundations own needs and everything else comes secondary. This is what it takes to keep a project like this alive, and they know it.
If I put a SD card with ex. Alpine Linux into a pi, it'll boot into Alpine Linux. If I put a SD card with Alpine Linux into a Pinebook Pro, it'll boot into... Manjaro.
EDIT: Actually I guess the Pi 4 added an onboard flash chip with an early bootloader, but I can't figure out if it impacts the boot order or changes how hard SD boot is: https://www.raspberrypi.com/documentation/computers/raspberr...
