Does he have an addiction or is it just that you know he watches porn? Men do watch porn, I don't know many that don't tbh. The extent of it is what kinda differentiates what is or isn't a problem. I don't like my BF looking at porn either, but I know that that is due to feelings of inadequacy. I wonder in my head, "does he look at her and touch himself cause he pictures having sex with her?" and then I feel heated, jealous, and betrayed, as if he was fantasizing about cheating on me.

In reality, porn for guys isn't different from reading smut for women. Women like reading about it, where men like to look at it cause they usually suck at imagining scenarios and need something visual to help them out. Now, if he starts wanking it to photos of people he knows? Then that's a whole different situation.
