> Amazon has been subsidizing it in the hope that people would buy stuff on a moment's whim any time of the day.

I think the deeper issue is that when Amazon started the product (I heard rumours of it circa 2014 or so?) Amazon was a trusted retailed. Stuff was cheap and generally good. Now it's a scummy marketplace filled with fakes and frauds. I'm not buying anything off it until I've deeply reviewed what I'm about to buy.
