Apple makes no promise of support for any of its products and never has. I would much rather use an Android device from a manufacturer or a desktop OS from Microsoft that is actually up front about their support lifecycle, than go with Apple that does not publish this at all. Some Apple devices have had much longer support lifecycles than others, and I don't think that's OK given how expensive their devices are. An iPhone 6 was supported through 5 major iOS versions (including the version it was shipped with). An iPhone 6S released a year later was supported for 7 major iOS versions. An iPhone 7 released a year later again was only supported for 6 major iOS versions. This wasn't documented anywhere when people bought those devices. Security updates for older iOS devices and macOS versions are sporadic and often incomplete.
