Yes you can turn it off but you've clearly not dealt with teenagers addicted to shit. With my nephew who got so addicted he wouldn't walk literally 10 feet to go to the bathroom (they found bottles of piss in his room), we tried all manner of things. Set time limits. If he didn't do his school/chore work they started by taking his Xbox power supply. So he then stole mine (I had an Xbox that I didn't use and I guess he found it somehow; he also bought another one that he hid). So then they blocked his Xbox from the wifi so then he got an ethernet cable and ran it to the router (which was hidden). I forget what he all did, but one other notable thing was he at one point had sold his Xbox (since he was basically grounded from it indefinitely at that point) to his younger brother (that was living with a different sister), but then didn't end up doing that (he kept the Xbox, but gave a suitcase full of like laundry or something). He did that to his own brother. I want to say they even caught him with an entire other Xbox (which he claimed he "borrowed" but pretty sure he stole it) which he would hide and then stay up at night playing. He even managed to spoof things so it seemed like it was something else so it didn't get blocked from the wifi. You'll note multiple things there is very clearly addiction behavior.
Oh and the nephew would refuse to shower. Like even if it in no way was going to enable him to get extra time playing he still would refuse. He even got to where he would run the shower but not actually shower to make it seem like he did. Its ridiculous behavior and exactly as described by those other parents.
So yes, some is parenting, but the modern world is built to be addictive. Be it food, content, or other (i.e. vapes, etc), lots of shit has been basically weaponized to be addictive and keep you consuming, and a lot of that stuff is very targeted at kids/teens, and games are no different.
Its not just made up shit either. When devs were trying to get away with their lootbox scams and that caused investigation and scrutiny, it was found out that game companies were actively researching how to make their stuff addictive in order to make more money. Fortunately because they're greedy dumbfucks, they got found out since, there's a reason there are strong laws about targeting children with gambling and their lootbox shit was definitely running afoul of that. Unfortunately, the same research they were doing for that they still were utilizing, they just ditched the exactly like actual gambling machines lootbox stuff and instead focused on ways they could legally get away with that in the core game.
