I actually don't hate this??? As long as parents can set up their own whitelists and it's not up to the government to have the final say on any particular block.
The problem of "kids accessing the Internet" is a purposeful distraction from the intent of these laws, which is population-level surveillance and Verified Ad Impressions.
But laws alone won't fix this, and laws aren't necessary (except maybe a law that prevents kids from buying phones). In the article, the child's devices had parental controls, but they were ineffective. There's demand for a phone with better parental controls, so it will come, and more parents are denying access, so their kids will become less alienated.
