I'm sorry, but what you are saying there is ludicrous. If it would really make energy "too cheap to meter" then no conspiracy could keep it back -- the people making it would have plenty of excess cashflow to grease the palms of potentially interfering politicians.

The truth is more mundane (and you should have realized something was wrong when you started thinking in conspiracy theories). The technology is simply not as great as you think it is, and like most technologies it's probably not going to win. There's no dishonor in that; the market is a brutal place.
