This is just my theory.
hlgg was made when Hololive especially EN was at their peak popularity, infact this place can't stop talking about numbers around myth debute until mid-2021. Now you could see EN is reclining in general, it's like you took out one of their best dopamine then they decided to push out any kind of data discussion to /#/.
I don't mind when you want to talk about numbers. I have watched Hololive when Pekora could only pull 3-5k live viewers and cheering for Luna when management put her in weekly box of shame, One day you can be on top of the world while the other day you can crashed to the bottom
