Well, looking at some different definitions for 'addiction', then most likely no. I love porn and regularly consume it since even before the internet lol. But there's no urge, no impact on life or any kind of harm. It's just something I like and do often, just like any other hobby.
I do have some kind of addiction of collecting porn (hence why I like it here), it's not like I want to collect all the porn of the world (I can't afford 9999999 TB right? lol), it's just that FOMO *what if this relic disappears?* the Internet has a lot of content but there's always the potential of good stuff being lost, so I like collecting good quality stuff, not only porn. There, that would be my addiction! I don't even watch like 1% of what I get, but collecting it consumes more time than I wish it did. However...no matter what you do in life you'll be wasting time, just be sure the reason makes sense to you
Update: I'm quitting today. Wish me luck!
