While I agree this is a pretty interesting idea in concept and theory, the big hurdle is going to be convincing people to leave the legacy social media platforms for new ones built under this framework, even if the intent is benevolent. The average person couldn’t care less about data privacy, and I can guarantee Meta/Xitter/etc will a) not abide by these standards in any way, and b) will actively thwart and do everything in their power to sabotage this. Unfortunately, regulatory action Is likely the only way to begin this change, which sure as hell isn’t happening under the current US administration, and without pressure at home, these companies won’t do a damn thing about it.
