@mmstick indeed when released phones have at most ≈7 years of update, which is not much, but phones usually don't live that long too. Phones with few years of update should (and will in the EU) be illegal and people shouldn't buy them.
Also, phones are much less repairable, and because of the end of life at ≈7 year at most, spare parts cannot be used to keep repairing them as long as we could while keeping the security it offers
