It's interesting that this manga of all manga is the one that first timers are choosing to practice on. If anything though, it encourages the actual groups to translate faster, so win-win for us.
@Nobody-desu well /a/nonymous is credited in a few of the SSSSS chapters, so they've probably cooperated on those chapters. I'd say they're cool with what SSSSS is doing, especially since both groups come from the same place.
I thought the new releases were pretty nice cuz they gave us a glimpse into Iruma's character development. It's not like it spoiler any twists ory anything that might sour the experience.
