why care??? We're just happy y'all exist.
But, if you want an actual reply to that, it's because there's
a lot of time commitment to those projects. We must know if it's worth translating the same manga as someone else, because we could just be translating a different manga instead. It's just not a logical decision to make on
both sides, someone will eventually have to give it up, especially in cases such as Neuro, which is a laaarge manga. It's a huge time sink, why do it twice when either side could just do something else that could benefit the manga community some way? The best case scenario for me right now is to cooperate and do it more efficiently.
It's a passion project for us, so we probably won't stop releasing it either way. I'm just explaining the general feeling of scanlation groups. It's honestly a pretty big topic to tackle, but overall it's just about the uncertainty that comes with having "competition" and the question that's raised: "Should I keep putting time into this if someone else can do it faster than me while maintaining a similar level of quality?"
Just to be clear, I really don't mind that Snail Scan's release happened. If anything, I'm happy that someone other than me and Suran who likes Neuro enough to want to do a rerelease exists lmao.
