I actually don't mind B/W comic at all. In fact, it can look more impactful and cleaner, not many visual distraction, and allows the utilisation of some interesting effects. Traditional black-and-white manga still around until now, and many people (including me) still like it and maybe prefer it over colored comics. I don't understand why webcomic readers seems to be repulsed with uncolored comics.
From the artist's perspective, no color does not mean easy. You still need to convey the atmosphere and everything in black and white, but making them clear enough as there is no color to distinguish. However it does not need extended rendering to look good, looks more consistent, and saves time.
