I like given ideas but am not optimistic about their success. Why? Because of the human nature ofc :) Where ever money is involved it will have some influence on choosing our actions. Quality of the content is relative; I think that good content is one with which I can learn new things or at least entertain myself but some people think Instagram-like content is better. Further, what you propose takes time and effort, to make content, to search through given, to engage in groups, to be interactive. More people, more content, more time, less those prepared to search through it; unlike fb where you have 1000+ but algorithm decides for you what you will see in news feed and makes it much easier. I can give me as an example, my posts not very visible and just few followers, I do not engage enough (my time has another priorities), even those upvotes that sometimes hit over 300 are mostly delegated votes.
Talking about awareness, learning, critical thinking...majority of people do not want that even if they say they do. Humans want it all, smooth and easy; if only that all can come without any effort. Actually, the most effort people put in trying to prove their point of view, justifications of their believes; if that much effort is put in open minded exploration and self-education, we would have much less Flatearthers :) and people who are doing this . Now you may argue that these are extremes, Hive has different social structure...but we should have in mind how many people produce and follow this kind of content on soc med, why scientific channels have much less views and subscribers that random persons and influencers...if not algorithm biased, search will always be human biased.
I can speak from experience, even when you have young people which are more prone to change, it is veeery hard to motivate them for education; meaningful learning requires proactivity and humans are, in digital era, even more into reception.
Freedom of speech is two-sided blade; we live in post truth era where people are not just entitled for their own opinion but so many proclaim it as the truth.
