Depends on the severity. If it is a slap that everyone and their brother can hear, then yep I call it and stop the layup. To me, the foul count, which is determining potential 1 and 1 or double bonus and for how much of the game a team has that benefit, has just as much effect (and maybe more) on the game as that layup.
If A1 bumps B1 from behind on a rebound but B1 gets the ball without being affected, are you going to call the push?
Again, depends on the severity. Slight bump, rebounder maintains control, then no. Hard bump, or where player is coming in out of control, but rebounder maintains control, then yep, I whistle that one.

Again, two good examples of where if you let all of this go as long as the offended player is 'not affected', is just giving a message to the defense that they might as well go for broke every play, instead of thinking twice on reaching, etc. Can't remember every calling more than 2 fouls on one player for a rebounding foul in one game. Usually after the first, and definitely after the second, they are very aware of the other players around them in a rebounding situation and make better decisions.

thats called hustle

what we are trying to explain is advantage/disadvantage -- 2 very key concepts in officiating

The fact is that the rules don't call it a foul without advantage or displacement of some sort. I'll ask the question this way, as it paraphrases your question to Mark.

When do you apply rule 4-27?

It's not a foul without an illegal advantage, so you are unfairly penalizing A1 on this if you call him for a foul; and you are unfairly adding to Team A's foul count.
