Computers, especially computers connected to the Internet, are too specific entities, so analogies often are faulty. Gadgets become obsolete not because Apple is evil, but because world is changing too fast. New websites are too heavy for old CPUs. Software evolves too fast, so it costs quite a bit to keep old hardware drivers up-to-date. Malware risks are real, so the option of not updating is unsafe.
Yes some typewriters from a century ago are still working, because their owners have put in the time and money to keep them working. They arent magic machines. They need parts to be replaced, cleaning, lubrication, obscure ribbons, gears, keys.
Similarly there are plenty of computers from the 50s and 60s still working, for the same reason.
