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).
That’s the first thing I thought as well - as long as Wikipedia remains open and public and free there’s a degree of transparency and accountability there -
But if you download your own separate offline version, it can be whataver you want it to be, and that will be all your users get - whether your goal is to ensure access to the ‘right’ parts, or to disappear the ‘wrong’ parts. You could even start out with the former objective, but end up with the latter situation, depending on how things go.
That isn’t quite the same situation with the definitive version of Wikipedia live on the World Wide Web.
I don't think it's productive to assume we know exactly why someone would use this, and how they would both implement this and discuss it with their children in their own home, and then attack them based on said assumption.
Do you think katabasis' proposal is unhealthy for a society? It strikes me as healthy for parents to keep their kids at ideological home during an information pandemic, to provide access to educational material and shelter from social media.
