I'm just trying to summarise to be concise, this part is what I was getting at

look at how little it took for the protest to wane, some subs are still protesting or migrating, but the majority reopened and they’re going on like nothing happened.

I disagree that "the majority reopened", of a total proportion of subs that blacked out I think the majority are either blacked out or have not resumed operations as normal. This is different from a majority proportion of all subs, which is a much larger number, and the majority of which also never participated in any blackout. Since the majority of traffic on reddit goes to a minority of subs, it's not clear which metric you're looking at or whether it's meaningful in context.

Since reddit algorithms to some extent relied upon that consistent operating principle of posts in popular subs being boosted, initially the result of the blackout was extreme - the website could not functionally aggregate posts on most users frontpages with so many subs on private mode. But that is not a problem directly caused by the blackout, it's caused by reliance on consistent data. So all reddit needed to do in that case was adjust the algo to significantly improve the average user experience during peak blackout. Instead of users seeing a bunch of posts about private subs they can't interact with, they just get fed posts from subs that didn't black out, so users could engage with reddit while an active ongoing protest was happening on the platform and might not even notice.

So I guess my point is that someone's impression of how the frontpage looked at t+24hrs, or t+48hrs, or today, as an indication of how reddit's going right now, is inaccurate because of the inherently subjective nature of the information visible from just browsing the platform.
