As to Rossmann being a hater, I too have seen so many stories of Apple denying warranty for made up reasons (liquid damage, etc) that it is very difficult to believe that Apple is acting in good faith when it comes to repairs.
Seems unfortunate that some environments are harmful to electronics, but what would you have them do, guarantee the product in absolutely any conditions?
Might as well step up and not shirk your obvious responsibility for covering impact events as well, since those occur fairly often in many everyday situations. Let us know how that works out for you.
I think it's entirely reasonable to support hardware sold in 100% humidity central Florida where Apple is licensed to do business (covered under the Magnuson-Moss Warranty Act.)
As to your second point, I’ve had only positive experiences with them with repairs both in and out of warranty. However some of that may be because I always buy at an Apple store, rather than at third parties, because doing so gives their systems more visibility into the detailed history of the specific item I buy, and thus they have more leeway and discretion to solve problems in very nice ways. It’s likely that many horror stories you’ve heard are dramatized after the fact by people who went for a sketchy discount purchase and want someone to blame. People do lie, and liquid damage is a real thing.
Apple got caught on hidden camera. Multiple times.
You can find plenty of these kinds of videos, but I think Rossman was referring to this one, featuring the man himself:
