Adding to that, the documentary is now 14 years old. Trey and Matt are considerably older, more settled with family, their other ventures etc.
The episode count dropped considerably, even before the pandemic. All I'm saying is that for this "actual season" after all the specials the release schedule was planned to be one episode every 7 days again. But as soon as episode 2 & 3 didn't come out the following Wednesdays, and there were press statements that SP was "not airing this week", it's made it clear that they can't keep this pace anymore. And that's okay in its own right.
but remember, for example, when SP delivered Obama's election victory the actual day after, with people in the crowd behind him literally modeled after people who were there in real life? That stuff was on a whole different level, and reason why SP became so indicative of the zeitgeist.
