The first premise of the case is that it's to protect the children, so this doesn't make any sense - it's not people with self-regulation improving their own environment. Parents are the ones who are supposed to make sure their children have limits, in general, not just for social media. Social media/etc. makes it easy (or can make it easy) with parental controls.

Even construed more broadly, this makes no sense. All of these cases and the criticism hinge on harms of addiction, that pretty much by definition apply primarily to those with poor self-regulation. Those with proper self-regulation need them much less - so it's basically paternalism. Supposedly some people don't know what's best for them, they are "addicted" to watching cat videos. As, again, is obvious in this case, since the case is literally about children.

I, personally, like infinite scroll algo reels. I probably spend about 20 minutes a week on them, and if anything I'd prefer the algo to be more tailored / "addictive" cause it tends to over focus quickly and bore me. It sure sucks at addicting me. I don't want the state to interfere with what FB can or cannot do with the algo. If an adult gets addicted to reels, they are definitely not a victim.
