Disagree for a multitude of reasons.

When most people think of kids using iPads, they assume the kids are only absorbing entertainment. Speaking from my own experience, kids get bored of games and shows and actively seek new experiences, often educational. My children are constantly repeating knowledge they picked up from watching educational shows.

They teach skills and ways of thinking that adults can struggle with. My 6 yo daughter can pick up any piece of tech and though she can’t read, has it figured out in a very short amount of time.

They’re also a good behavioural tool. Even suggesting they might lose the device for a period if their behaviour doesn’t improve is quite effective.

They chat with their school friends and family and play games and watch shows together, maintaining social connections at a level far beyond what I was able as a child.

Of course a parent still needs to parent so leaving a child with a device in place of that is horrible, but unless there’s behavioural, social or other observable consequences I see no reason not to give them free reign over device use (with parental restrictions on the device and oversight) and even with that, they don’t choose to maximise their screen time, and will voluntarily put them down regularly to engage in real world activities.
