I left this [1] comment a few weeks ago, and I already knew people like you would have dogged on GP for giving their child this level of access and autonomy, just like I knew the HN thread from the other day about homeschooling was going to dog on people who allow their child to go to public school - because teaching children self-sufficiency, self-assurance, and confidence to deal with bad influences is a relic of a time gone by.

Parents would rather justify to themselves the act of building, end-to-end, what their child is exposed to and around - even when that's not how the world works, rather than building a child that knows how to handle themselves when exposed to, and around, anything - because that's ACTUALLY how adult life works.

There's levels to it, and I understand a child can have all the tooling in the world about how to deal with bad influences, and neglect its application solely due to naivety; but it's still a lot more fruitful than just hand-picking a child's exposure to any and all things during their most formative years - when they're SUPPOSED to be learning how to deal with exposure to as many things as possible, good and bad for them.
