Me and my brother used to patch holes in our jeans with iron-on patches, same idea.

Totally agree with you, it's not just sensors either. I've noticed this same thing with ALL kinds of tech and even just regular house stuff. Like my wifi router acts up WAY more when the weather's on some weird schedule. And my car's tire pressure light freaks out every time the temp drops fast. It's like everything is hyper sensitive to the little shifts we don't even think about. That's the thing about living in a place with real seasons or a desert, we're just used to fighting the environment constantly, even our appliances are in on the battle.

Gotta defend the stuff though - if you actually follow the directions and leave it in way less time than you think you need, it gives a nice subtle tint instead of turning you into a creamsicle. User error is usually the issue with these things, not the product itself.

Oh man that is brutal, I felt that one in my gut just reading it. Did you try lifting the grate at all or was it bolted down?

My fridge is a warzone of old leftovers and I've never had a single issue with film stored in there for months. I keep my rolls in a ziplock bag in the crisper drawer right next to rotting veggies and they come out fine. Honestly think you might have had a seal issue or maybe those rolls were already compromised before you put them in. Tbh moisture damage sounds more like a freezer burn situation or bad caps, not apples.
