This is looking at it from the wrong side though. It isn't the hardware vendor ending support there, it's the software vendor.
PC hardware can be supported indefinitely because it's documented, more or less. Windows uses a hardware abstraction layer so the old drivers can be used with the new Windows. Hardware only stops being supported by Windows when Microsoft decides it, not Intel or NVIDIA or Broadcom.
The Linux community writes open source drivers, or the hardware makers do themselves, so they can be updated by the kernel developers when they make changes to the kernel and continue to work. You can put run the latest Linux kernel on a PC from 1995.
But for phones the hardware support comes as an opaque binary blob tied to a specific kernel version, so when that kernel falls out of support, the hardware is slag unless someone has the resources to reverse engineer it. Which they might if it was just the wireless or just the storage controller, but it's not.
