Despite the name, "corporations" and "limited liability corporations" don't magically protect the owners and operators from liability. You're just as liable for the shit that happens under your corporate structure as you'd be under a sole-prop structure. Only once you add distance between ownership and operators do you start to have the separation of liability, but even then you can still pierce the corporate veil if there is a clear liability for the shareholders.
Its not a magic get-out-of-responsibility-free card. It IS a way for you to own 10% of that business and not have to stay up at night worried that they're going to arrest you for some shitty employee behavior since you have a board that hired an operating manager and that person did a shitty thing. The company gets fined, that guy gets fired, you lose money on your investment, but your "liability is limited" in this case to just the money.
Supreme court decisions like "Citizens United" said that you can have free speech as an individual, and that doesn't go away when you become a group of people (like a company). Unless you happen to believe that "free speech" isn't a protected right for CNN, WaPo, NYT, et. al. who are all incorporated entities.
