That's how practically all hoods in cars are, the water is allowed to get in because there is no seal on the edge of the hood and that area is expected to be exposed to water. Most people don't notice in other cars because people rarely have a need to open the hood. And the water is just on plastic in that picture, so it doesn't affect anything. That specific post is from a car wash, as pointed out later in the thread, if the car moves at speed, that water will go out the edges, plus car washes tend to have pressurized water that is different from rain.
And note the aftermarket latches are failing even on the 3, even though the frunk latch is within the weather sealed area for the 3, so what you pointed out is a red herring anyways.
As per the accounts, the failure of the aftermarket units is because the control boxes and motor units are not weather sealed nor are they designed for high humidity environments, so moisture can get in even if water doesn't directly hit it. Then the control box or motor eventually fails over time. That's why there's been so many versions released (including band-aid solutions like rubber bags).
Problem with Hansshow Support
I personally have a humidity sensor in one of the quarter panels, which doesn't get any direct water when it rains, but humidity levels still hit 100% when it rains (as expected, given there are no air seals to seal the area). Any parts in those areas that are not designed to deal with the high humidity will eventually fail.
