Those who address it are affected. People who don’t care, don’t feel the need to talk about cutting anyone off. It’s a defense mechanism to protect their internal feelings instead of accepting that people will disappoint you or let you down. Yes, it’s good to set boundaries but it’s okay to say how it made you feel. On another note, we don’t know why people cut people off. It could be the most valid yet pettiest reasons.

I believe it is about choosing themselves over things that don’t align with them. However, this can be a flawed mentality because there are always two sides to the story. Cutting people off for the sake of protecting one piece without taking into consideration the other person's feelings is straight-up selfish
