Like the title says, what are the damage mechanisms when there is no current flowing in the electronics? Additionally, what methods do hardware manufacturers use to “waterproof” electronics?

Couple different ways.
One important thing to understand is that it’s pretty difficult to get all the moisture out of, say, a laptop.
People spill a drink on their laptop, let it dry for an hour or so, and then turn it on… but there’s still liquid inside and causes a short somewhere.
I had somebody recommend allowing a laptop to dry out for a full week – while placed keyboard-side down on a towel or similar – before attempting to power back up.
(Source: My kid has damaged a couple of computers like this – I’ve had extensive conversations with the local repair guy.)
The other big problem is that moisture can lead to corrosion of important elements. (I’ve had to throw away more than one pair of cheap ear buds because the charging terminals would corrode due to sweat.)
