My statements are quite logical. You dreaming up words that I haven't said is not.
In terms of your final statement, I said nothing about safety, so you're wasting your time with whatever point you're trying to put forward.
You might also want to listen to the engineer who's post above backs up the main point of the argument, which you've lost by dreaming up things that haven't been said here, that people shouldn't worry about their electronics being hot provided that the ambient temperature is within designed limits.
Wow dude.... You deny that you mentioned flying and safety in the same sentence? I believe 2 people quoted it so it is stuck in the record now... I am going to stop with this thread as there is no hope.
As for your last statement on temperature.
Ambient temperature is the temperature of cabinet that the receiver is in, not the room temp (which I am sure you are aware but many aren't). Keeping ambient temperature down requires ventilation which is often unreasonably specified.
Here are the ventilation requirements for the 1120-k. They ask for more than 15 inches above the AVR, more than 7 inches on the sides . Do you believe that everyone meets that? If they don't then they can't really use the full feature set of the AVR as it is specified.

Do not install this unit in a poorly ventilated area, or in
locations exposed to high humidity or direct sunlight (or
strong artificial light)
When installing this unit, make sure to leave space
around the unit for ventilation to improve heat radiation
(at least 40 cm at top, 10 cm at rear, and 20 cm at each
For quick reference:
40cm = ~15.75 inches
20cm = ~7.875 inches
I don't meet that on my equipment and know that a lot of people don't. In my case I add amplifiers and cooling fans to help. I also observe 115 degrees F on my HDMI board without a fan when the unit is doing no amplification. That in a small cabinet will easily surpass the 95 degree F max temp.
As for design specs and functions... My car says it will do 0-60mph in 6 seconds. Based on similar thinking to yours that means I could infer that it is okay to accelerate 0-60 right out of my garage every time I start out for work in the morning with the engine cold... I don't think the car would last long that way...
Should we all try the 0-60 cold engine test every morning for the next 6 months and call you if one of our engines fails?
We could probably get them covered under warranty but it still wouldn't be good for the rest of the car either. Then there are also those of us that would like to have the car last beyond its warranty period....
