Didn't Apple say a few years back that no screen protector was needed, and even went as far as to remove them from stores?
If I recall, what they were saying was, that screen protectors aren’t necessary, they’re optional given smart phone displays are generally durable against Minor objects with little impact . I’ve never used screen protectors on my phones and even if it has minor hairline scratches, they’re hardly visible. It’s just like a protective case for a smart phone, it’s an optional accessory, you don’t need to purchase one. It’s merely added protection, but the display itself is perfectly fine against most slight impacts with keys, coins, ect.
