The fact that you don’t believe it doesn’t make it any less true. The funny thing about what you’re saying and what the rest of us are saying is that we were there and experienced it first hand, and you’re just an opinion.
My iPhone 8 was 10 days old and was treated like a newborn baby. There was absolutely no damage on the device...it had been placed in an otterbox as soon as it came out of the packaging, it was never dropped, for christ’s sake it had never even seen a drop of rain! No...the thing spontaneously cracked and went into boot loop. That’s the simple fact. I was there (you weren’t). I experienced it (you didn’t).
My last iPhone was a 6 s Plus. It fell off my treadmill one day and I stepped right on the home button area. Absolutely schmucked the thing. The screen cracked and fanned out all the way up the phone. It was so cracked that the glass around the home button actually became a bit sharp. The screen was a complete write off. Oh...except the home button, which came out totally unscathed.
So, while I realize you are a random internet expert like so many others, it’s apparent you need to give this some more thought. The home button is made out of sapphire glass, and is recessed in a device that in many cases has a protective case and/or screen protector on it. Short of someone dropping a heavy metal spike exactly on the home button, there is next to nothing in the way of an “incident” that would CRACK a home button and not also do damage to the screen/screen protector around it.
