Just guessing but maybe the poster meant that those things don't attack root cause which is sad but simple - screen/media addiction and easiness of obtaining next kick from it, versus actual physical relationships which are much harder to manage and it only gets worse with age. They help you existing around this gaping dark hole but not doing much with it itself, just trying to divert you staring into it. Well guess what, its now part of you, permanently. Admitting that to yourself ain't an easy task on its own, especially if one works with IT or with computers all day.

With that being established, addictions can be tackled in numerous ways, but lets be frank here - our mind, often our greatest asset, is our greatest enemy with addictions. An addict has a permanent crack in persona, something you can put some glue in but things will never be the same as before, you are in recovery for rest of your life.

Since screens and media are everywhere, its pretty hard addiction, similar to say cigarettes in terms of shedding it off. So I think all those tools mentioned work to some extent, for some, but actually getting off the drug shows different, more intense results. The effects are quite subtle unlike say heroin so there isn't societal outcry yet, everybody just complaints about 'kids these days' and moves on.

That's why I consider criminal to let small kids play endlessly with phones/computers or sit in front of tv all day, getting their first addictions from their own parents who are often deep in their own rabbit holes.
