@CoolOtoMegane he's using it to train and compare with ZeroScans releases.
He could do it with older chapters and not release anything but why not release new chapters so he can get feedback on the quality of his work ?
He could do this with dropped series but then he wouldn't have anything else to compare to.
It's not like it hurts anyone, ZeroScans will release anyway and most people will either wait for them or read them to compare with his release as most are expecting better quality from ZeroScans (which in no way is an "insult" to 123, they've just been around long enough to give us these expectations).
I don't why there'd be any drama at all.
@towerofgod123 you could get in touch with them to see how they work and learn a things or two I guess ? If they're willing, that is.
edit: I've read both versions and... tog's version is really great even when compared to ZeroScans'. There are a few times where I prefer ZS' because they fill the bubbles a bit better, their "heavier" font when someone is shooting looks like a better pick, TL notes are great (in my opinion, I like when something gets lost in translation but the TL tells about it), and a few word choices are a bit better sometimes ("Same here" on tog, "That makes sense as well !" on ZS). However tog's got a better font and size overall, the fact he used something to make the raws look better is a huge bonus, got to afk so I'll cut my comment short but tog's version is really nice.
