People don't care about "what companies serve them". They only care if the children see sexual content (or things considered deviant). Once sexual and deviant content is filtered, they're happy to give away their children's development to the company's algos.

In effect, the people don't want to concern themselves with what their children consume, unless they're outraged by things normally taboo in their age group. Besides, if everyone is in it "it's not that wrong". They seek reactive entertainment rather than proactive engagement in their children's development.

They're called politicians.
