The modern internet is filled with content designed to track, mislead, and manipulate users (especially young users who don't have a full set of critical thinking skills). I think it is totally appropriate to want to give families (not the state, FWIW) the tools to take back some control.

Giving kids accessed to a curated experience online sounds much more feasible than keeping them offline all together, but most parents don't really have the technical know-how to do this themselves (and tech giants like Google, FB, etc. are not interested in providing these capabilities).
