That sounds like a terrible idea because it would progressively "bribe" the government to be in their interest to take the company's side as they gain more and more of it. Combine it that conflicts of interest with the appearance of improprirety and another conflict of interest of making expropriation of the successful a temptation.

The latter could be even more disasterous long term. Nobody wants to go out to dinner with cannibals or show up at the stores for fear of being eaten. Likewise being known as an expropriating country, you may as well go ahead and embargo yourself.
