Until most kids are about 12 - 14 years old, they're learning much more basic concepts than you're describing. I don't think anyone is trying to take intro to computer science out of high schools or preventing an advanced student younger than that from the same.

I would rather a teacher have to draw a concept on a board than have each student watch an animation on their computer. Obviously, the teacher projecting the animation should be fine, but it seems like some educators and parents can't handle that and it turns into a slippery slope back to kids using devices.

So for most classrooms full of students in grades prior to high school, the answer to your list of (presumably rhetorical) questions is "Yes."
