Besides direct control, what could a dividend on the profits do what a well-proportioned corporate tax on profits cannot do? The state would only get dividends assuming it would not sell shares. And the state can exert control much more fairly (ie. to all competitors as well) with regulation and laws. Regulations and taxes are seen as 'un-american' I suppose, while giving stock to the government is not somehow?
Under normal circumstances the government owning stocks is just as un-american, but nothing is normal when it comes to AI.
