Am I being unreasonable?

So my husband I disagree completely on screen time. He watches TV most of the day on the weekends. my stepson has been allowed to be the same way. Stepdaughter is always on her phone. But when my son was born I wanted to limit screen time. My husband does not care and has said he thinks I am a nag. And by limit screentime I mean that at 2.5 years old I think one episode of Puppy Dog Pals per day before bed is enough. Husband lets him watch whatever he is watching which is not always appropriate. And of course my son wants to be by his dad sometimes and I can't keep locking us in my son's room everyday. I try to set an example by limiting my own screentime and reading to him and in front of him.

My question is, does this seem like an unreasonable hill to die on? I am getting so sick of fighting about it when he just does whatever he wants anyway. It is infuriating but I feel bad for my son having to be cooped up in his room and me always having to be the one to limit his screentime. At some point it just turns into me being the bad guy and his dad being the fun one. Any advice? TIA
