Kind of a big difference. I never get a "rate us" pop up in the middle of playing a game or interacting with content or something substantial. I always get them when I log in or return to a home screen.

Apple is popping up in the middle of content interactions. Never before has there been this type of confusion if you were rating the content or the app because NO ONE ELSE pops these up in this place.

It's kind of the difference between giving a lit match when they aren't holding gasoline in their hand and when they are. Maybe a bad analogy but other developers aren't throwing matches in that moment and Apple is.
Anecdotal confirmation bias. Just because it has not happened to you (as far as you can recall) does not mean it has not happened. I have had it pop up at random times with some apps.
