Any large company with half-way competent legal counsel is going to tell their employees not to say, "our goal is to crush our competitors, dominate the market, and hear the lamentation of their women." Instead they will tell their employees to focus on making life better for their customers. It's a much healthier way for product managers to focus, and what you might do if the goal is "crush/dominate the competition" is *not* the same than if the goal is delight the customer. So it's not just a messaging strategy to prevent embarassing e-mails from coming out at trial; it's a business strategy, too.
