Yoshida (2016, Gamescon): "It's alright not to play it everyday. Since it's just a game, you can stop forcing yourself if it's hard on you to keep that up. Rather, it'll just pile up unnecessary stress if you limit yourself into playing just that one game since there are so many other games out there. So, do come back and play it to your heart's content when the major patch kicks in, then stop it to play other games before you got burnt out, and then come back for another major patch. This will actually make me happier, and in the end, I think this is the best solution I can answer for keeping your motivation up for the game."

Translation: "Feel free to unsub, take a break, and come back when you want to."

So people are just taking his advice. Nothing else to see here as people are playing other things since they did the content they wanted to. I am personally just going through a back catalogue of games I have like RDR2 or Elden Ring.
