I know its easier than ever to dunk on how terrible reddit has gotten, but honestly? What is this? How is is safer to deliver this content to kids viewing reddit on a tablet or PC or in the app? Why even create the bs excuse?
They could just have easily told the truth an displayed a message like “Content is limited. Open in the app to view.” It’s still a jerk move, but at a minimum its honest.
What concerns me the most (I’m not a parent) is the advertising and deliberately addictive games. I think forcibly shutting it off is not a good idea as you are basically becoming a drug dealer to the kid.
Maybe make them willing shut it off instead of forcing it off. If they aren’t mature enough to do that they either the software is terrifyingly addictive or they are to young.
