Yes, but I'm guessing kdragOn's legal budget is a whole lot smaller than Docker, Inc's, so the perceived risk of stealing the product would be a whole lot smaller.
Most businesses are honest, plus once you get to a certain size, it's all about CYA, so sure, some people might plunder it, but if you provide something a lot of people want, you could make plenty of money from the legitimates or people afraid of getting sued at some point.
Then once the business is viable, the legal budget will be bigger...
