My understanding so far is that as humans we get bounded by our emotions, morals, incentives and fears. On the other hand you are competing against capitalism that tries to use any possible means to make profits. It treads along every possible path of whats not completely illegal. What benefits it is that either the laws are not yet defined to cover those situations or they are hazy enough that there is an escape hatch. You name any big company and they have gone through the path of doing something that was illegal or questioned. Just like critical mass or escape velocity, if you are big enough you get through the hurdles or otherwise you get stuck and make a good topic in some ones paper like this.
