I don't remember if this was discussed before, but I was thinking about it and can't see the reason behind this rule... why does having a logo on a corner or edge helps?

I would guess that you can sometimes feel a logo, so having it on a center reveals much less information than having it on an edge. Yes, you could get extremely picky and say no logos if they can even be felt a tiny bit, but that's probably overkill.

really? I can't feel my logos (on normal stickers) but is that seriously an advantage? I mean...yeah, maybe you can feel the white/blue/orange corner, but does that help you?

Like with the transparent cube, it's just easier to not allow it than it is to determine how much is acceptable, and where the line is crossed.

what about damaged stickers? you can feel it if you "practice"... will we just allow perfect stickers?

If you can feel it, see Article 3i. With a logo on an edge sticker for instance, you may identify the piece without having to look at it from behind (you see white with logo, you know it's white/blue and not white/green, nor white/orange, nor white/red). That's what Article 3l is for. Why only one? Well, official cubes have one, and it's a puzzle, not a piece of modern art.
