Why NBA hasn’t fined Jazz or even Celtics

I am wondering why nba fined other teams but jazz aren't with them BLATANTLY reporting rest for their players - sexton, collins, KESSLER (A 23 YEAR OLD WITH A ROOKIE CONTRACT), markkanen etc. It's only JANUARY. Even celtics are doing it from last season. However, recently they fined the hawks for example for "resting" Trae in which he has a legit Achilles soreness injury?

I think if they're going to fine one team for doing it then they should be doing it on other teams as well.
