A lot of parents lack sophistication when it comes to "screen time".
I have multiple in-laws who seem to not understand that it's what is on the screen that matters. As you predicted, those same people are also prone to magical thinking about other things: vaccination, fluoride, radio waves, GMOs, etc.
This has multiple effects. First, they tend to over-limit access to useful aspects of computers. Second, they tend to allow toxic uses of the screen-time (allowing an hour of pocket slot machine time each day, which is IMO super excessive).
A stretched analogy: it's similar to a parent who doesn't understand the difference between alcohol and water, and therefore limits their children's access to liquid to a few times a day. However, during those few hours, the kids get to drink whatever they want out of the liquor cabinet. Obviously, the cabinet should be off-limits 24/7 but the water faucet should be freely available.
Similarly, kids should not be allowed to play pocket slot machines or watch youtube with zero restriction/oversight. But there's nothing wrong with allowing near-infinite screen time for other uses, because it's not the screen itself that's the problem.
Concretely, my kids will have unrestricted access to an Apple ][ with an Apple BASIC interpreter and manual. I doubt that will cause any problems that aren't also caused by unlimited access to microscopes or pH strips.
Of course, their access to iPad games and Netflix will be moderated in the same way their access to TV will be moderated.
But a lot of parents -- especially non-tech-literate parents -- lump it all in as "screentime", which causes them to both under-moderate what's going on when the screen is on and over-moderate access to the screen for healthy uses.
