That's where the constant disclaimers to the effect of 'the views expressed do not nessecarily reflect the position of the company blah blah blah' whenever someone speaks who isnt the principal executive of the organization. The problem being though it doesn't go both ways, when one of the high leaders speaks it's portrayed as 'our company believes' which then at least somewhat implies the employees of said company are in agreement. Individual expression is just leveling the field by letting the employees say 'the views of the company do not reflect my own.

It's less common for any smart business to make highly charged statements unless they happen to be sure the majority will support them for it, but not unknown. I've seen a couple small ones around here that went as far as to plaster Q slogans all over their signs. From a business perspective they just alienated a major portion of their potential customers without anyone setting foot in the door.
