So what? Every individual in that corporation is free to do as they please, *as an individual*. As a corporation, with the corporate veil protecting every individual from personal responsibility for their actions, they should not be allowed the same rights as an individual who can be held accountable for their actions.
Remember, corporations are *specifically* designed to allow individuals to accumulate profit while being shielded from virtually all risks beyond losing their investment. Such a protection is anti-ethical to responsible citizenship.
As a compromise, if we extend more rights of person-hood to a corporation they should come with corresponding responsibilities. For starters how about we make the CEO legally responsible, personally, for the actions of the corporation? Someone dies due to corporate negligence, the CEO ends up in prison on manslaughter charges. Suppress evidence that your product causes cancer, the whole board of directors is locked up on charges of conspiracy to commit mass-murder. A modern-day corollary to the notion that the captain should go down with the ship - the person who exercises ultimate authority must also accept ultimate responsibility.
