If you are using a word by its most common definition then sure. Addiction has more casual definitions in the dictionary.
Language evolves and the word addiction has evolved. It's used casually all the time like this blog post although there's no formal diagnosis.
Your examples bring up a good point. Many parents have the TV on all day in the background because they were raised with it. Many kids today will likely have streamers on all day as they grow up because they were raised with it.
It doesn't matter if they are good citizens or doing well in life, you can argue the perspective that it could be "harmful" if using the most common definition that many common mediums (radio, TV, internet, live streaming, etc) removes the sense of reality from people and promotes them to engage in consumerism/capitalism. That can be pretty harmful over the course of one's life although it's non-obvious.
I personally like the definition of addiction from David Foster Wallace. I couldn't manage to find the exact quote, but it's something like:
Addiction is when something purports to solve the very problems it creates.
Certainly not a standard definition, and might not be true in every case, but an interesting way to think about it. In the case of Youtube, watching videos might seem to solve the problem of loneliness and disconnect with the world, while actually exacerbating those problems.
DFW and his work definitely helped shape a modern definition of addiction. Much of the work I linked were inspirations to his work and ideology. I think most famously, DFW did not have a TV because he knew about his addictive personality and wouldn’t look away.
