In a few words:

 - No upside. There is absolutely no upside whatsoever in revealing the strategy to the public. Rule #1 of business, don't give away your strategy. If you do, it's for pushing around the competition or raise money. They don't need to do any of that right now.

 - You have no power. if FC had wanted to run away you could not do anything about it anyways. Info or no info.
 With info: No one would want to buy your shares.
 Without info, you would not know, but the market would be so thin no one would buy.

 - You have proof of honesty and no proof of dishonesty. Honesty is demonstrated by track record, products shipping and conference. Not by incessant online blabbering ("communication"). Cf. all the other scams who gave ample information about things that did not exist.

A final word if you are still not convinced: if AM was a scam, they would try to unload as many shares as possible at a high price. For that they would communicate a lot and build expectation to jack up the stock price. That did not happen.

Investing is not for everyone, you need an attention span of months and determination. If you don't have the necessary attention span, it's called speculation. AM has designed its business and communication strategy to attract investors and shake off the speculators. This situation is ideal, the insecure are leaving the boat so that only the ones with strong will stay - therefore the stock price will be steadier over time.
