> Apple can do it because they lock you into their walled garden where they can double and triple dip on getting your money.
Nonsense.
It’s because they have all the expertise in-house anyway, they get extremely good terms due to their weight and negotiation, and they figure if you don’t change phone now you might do so next year and they’ll get your money anyway. There’s no brand loyalty on the Android side, and fostering it seems impossible (even brand recognition efforts don’t seem to do much).
On what is based your claim that it is impossible to foster brand loyalty on Android side?
Maybe there is a reason that there is no brand loyalty on Android side, a reason that maybe those brands created themselves after seeking instant profits above anything else. Not one android phone manufacturer tried to cultivate long term relations with their customers for any reasonable amount of time. A lot of customers tried variety of android phones exactly for that reason, to find a brand that would not let you down and yet very quicly all promises were broken.
It's cheaper, in my opinion, to get a refurbished mini desktop from Lenovo or whatever. They're "real" PCs, and I've found the raspberry pi hardware limitations to be onerous. It's just really nice to have SATA, NVMe, and PCI Express lanes/slots. For the price of a couple of PIs, you can get a powerful CPU with loads of RAM.
