in my opinion, yes. the point is to make it less addictive- and this will take away some of the ‘fun’ without isolating kids. social media is entertainment that has been branded and marketed as an essential by the people getting rich off it. i find plenty of good things on youtube without ever signing in - i just search for them. if youtube or whoever wants to use its own ad space to promote channels, i think that is probably ok - provided that the choice is not personalized by an algorithm.
