> Should I be able to sue McDonalds if I let my kid eat 100 of them in one sitting?

Should you be able to sue McDonald's if they delivered you unlimited cheeseburgers for free, said nothing of the dangers, and even encouraged you to eat more, and then you became obese/sick from it? Sure, it may have been your choice to accept/eat them, but you did so uninformed, and based on false premises, and the risks were hidden from you, or even explicitly downplayed.

That's what social media is. It's free delivery of unlimited cheeseburgers, but for your brain.

In the above example, you were tempted with something that seemed good, but that carried great risks, to generate business for another who knew of the risks, but either didn't tell you, or even lied to you. When the risks backfire on you -- the risks they knew about from the very start -- or even have already been backfiring on you for a while, I think it's absolutely fair to blame that business for knowingly tempting you into it, and that it's also absolutely fair to seek damages. Proving those damages is another matter, but I think it's absolutely fair to try.

Worse, people have a limit to how many cheeseburgers they can eat at once. You can spend all day on your phone.
