The downvotes are interesting to me. Apparently Hacker News readers think Hacker News isn't social media. The ratio of user generated commentary to content on this site is 1000:1.
Is Substack social media? I don't know. We can't measure (don't know) what percentage of Jon Haidt's audience came from people who heard about his books or saw him on TV appearances. He should have a dashboard showing what audience comes from Reddit, Twitter, Facebook and syndicated news (like Business Insider). Substack is social media in all the ways that matter - it wouldn't exist in the absence of Twitter and Facebook, surely, and syndicated news like Business Insider which would cease to exist in the absence of Twitter too.
This is to say that the reason media critics are hypocrites is because they're really saying, "Anything that amplifies voices or ideas I like is good, especially mine, and everything else is bad." Like yeah, sure Jon Haidt, maybe your opinion about TikTok would be different if you were a successful influencer on it. You would simply say that there are more good things than bad, and that you shouldn't throw the baby away with the bathwater with it, or whatever. Well I think Substack is just a bunch of low effort syndicated opinions, but I have the wisdom to not say we should get rid of it, or that because Substack is stupid, people reading it are stupid. It wouldn't be true, but it would be a vibe.
I'm not sure if anyone is immune to media criticism hypocrisy, even Alexandria Ocasio Cortez criticizes Facebook while in the same breadth spending millions on political advertising on it. What can we do?
