How come only Kendrick gets to dictate when the beef starts and ends?

I don’t get it like if drake just shot again does that mean the internet would push Kendrick to respond. Probably not considering the double standards. I’m just wondering why there was no pressure put on other rappers to respond to drake like rocky and Kendrick for example. Like why did Kendrick get to decide when it was over idk if anyone gets what I’m saying but it seems like only Kendrick is allowed to start a battle because of someone starts with him they won’t push him to respond.
