Because they enjoy the show and they want to see it continue. Like it's not that hard to understand why people are upset with MHA ending. Like I'm sure it hurt people when shows like Adventure time ended or regular show, or Futurama the first time. Like people are always gonna want him to continue. Like I get he wants to make a new series, but I would very much rather see some more MHA

Honestly the jacket jacket fruit and the pile fruit would work surprisingly well together. Because from when I'm aware of unless I'm wrong the pile pile fruit allows the user to fuse with other people, and use their skills. In a jacket jacket fruit does the exact thing but for just one person. So just imagine you use the pipeline fruit on a bunch of strong people who had very good haki and physical strength and then you had them put on the jacket jacket from either, that way you have an overpowered monster with multiple different people's powers at your command.

Literally none of these courts are selfish.

Muscle augmentation doesn't make muscular a bloodthirsty brute. Like he said he just likes to kill people it has nothing to do with this quirk

Brainwashing doesn't take over someone's mind it takes over their body. Like Shinso said he can't make someone his brainwashes tell them something he doesn't know.

Stress isn't selfish enough why it is it just makes the person stronger the more stressed out they are.

Toga loving to drink blood may be because of her quirk, that doesn't make her selfish she grew up the way she did because everyone saw her as a freak for drinking blood. I mean Stain's quirk requires him to taste someone's blood, and he doesn't enjoy blood

Super regeneration just makes it so someone can handle injuries better than others

Finally All For One may seem greedy because it allows someone to take someone's quirk, but it also allows the user to share course with other people as all for one showed how quirk can help people by taking a quirk open from someone who doesn't want the power and giving it to someone else who wants power
