Why have there been barely any manga threads?

Chainsaw Man just started Part II and is becoming digitally published simultaneously on Shonen Jump's digital service, which I thought was interesting. Are most new series like that now?

The first part (11 volumes) was pretty great, and I assume when the anime comes out it'll be another massive success ala Jujutsu Kaisen, MHA, Demon Slayer, etc. There was also a great one-shot the same author put out this past year called "Goodbye, Eri".

So I figured, what the hell, I'll try Fujimoto's first series that made him famous, "Fire Punch". God, what a mistake. It's the most dire, edgelord-y shit that I guess I can't tolerate anymore - just as many offensive shock moments as possible in a fantasy apocalypse world featuring the absolute worst of humanity. Like The Walking Dead or Berserk, with even less hope. First volume alone has evil superhumans, child rape, slavery, "heroic" cannibalism, torture, and ends with some attempted bestiality. I'm eBaying this immediately just to get it out of my home because it's too late to return it.

Just wanted to rant into the ether in case someone else here also has had this experience...
