If a brand sponsors you, then you have to, so if your not sponsored you should be able to put anything you want on your skis. And when like 100 kids have your skis, stickers are the only way to keep your own flavor. Also good vinyl die-cuts are a pain to get off, hence adding a little security, my skis would be id'ed in a second, due to decals. But they must be done right and tasteful, I hate like weed leafs and naked chicks, stay classy!
