I actually made this argument many years ago on this forum and was mostly chastised for it.
I don't understand how someone can claim water resistance, and even give specific parameters, but then deny all water damaged warranty claims. In my eyes, one shouldn't even be marketing water resistance at all if they reserve the right to deny water damage.
Before I get chastised again, I get it. There's no tangible way for Apple to know whether you dropped the phone a mile deep in sea water or you dropped it in your kitchen sink while doing the dishes. The problem is, the burden of proof really shouldn't have to be on the consumer. They could just... not advertise water resistance.
I also get that other companies make similar claims. I don't support those either. And I'll never justify one company's problematic actions with those of another.
