From the article, "On one hand, Nintendo has the right to make sure content it owns is portrayed in the way it wants. It also has the right to make money from its property. But there is a grey area here that I think goes beyond copyright law. Let’s Play videos are, in a way, a form of free advertising. Content creators build up loyal audiences and turn them on to games they may not have otherwise considered. These videos also result in additional game sales for video game companies. It’s reasonable to think game companies overlook copyright claims because it’s getting something much more valuable in return – new customers. They tell their friends, those friends tell other people and the trend continues. However, this is obviously about money to Nintendo more than anything else. And for that, it makes the company come off as petty."
