It's not a problem at all.
The issue here is that no one else is doing it. So people bitch and whine that they can't find free stuff.
However the Advocacy decides to release their stuff is up to them. And as the only one releasing it, they can do it how they want. If they don't do it, literally, no one else is, so it won't be available freely anyway. So it's a moot point.
If another group picked it up, and started releasing chapters, then the Advocacy way of doing it would indeed make less sense.
If the people of Reddit, haters, or whatever, REALLY want the manga translated, they should stop bitching about how the Advocacy does it, and try and convince someone else to do it.
