To be honest, being a "mobile advertisement" doesn't bother me either way. It's actually extremely difficult to buy a cycling jersey without at least some kind of logo on it (admittedly, some are smaller than others). Even my Cannibal factory seconds jerseys have their logo on them. At least Vegemite is something that I personally use, which is more than can be said for most of the advertisements on other jerseys I see around the place.
