Personally, it's about teaching a child to actively seek out information vs passively consuming it. I love programming because it is interactive and I learn continuously. I want to teach my kids the joy of learning by doing. Hence the limitation on passive forms or consumption, like the television and the emphasis on activities like story telling, Lego and drawing.

FWIW, I found the very best method to help kids learn to actively do things was letting them do the things they chose to do instead of mom imposing on them her will and deciding for them. But that seems to be an enormously difficult concept to convey to other adults who seem to have no real understanding that the most important ingredient here is personal agency, even if they are only 2 years old and just want to do things that seem rather silly to adults.
