Your point is that Monsanto believes it can highly profit from the GM terminator technology, and I believe that is an accurate and highly important point.
In the late 90's, Monsanto was at the point that it could broadly deploy terminator technology, but pledged not to do so, and claimed to hold no patents on terminator technology (Terminator only, Monsanto holds many other GMC patents).
Monsanto then acquired outside companies that held terminator GM patents and again pledged not to use them.
Four nations signed on to Monsanto's patents and pledge, the US, Canada, Argentina, and China.
The rest of the world banned Monsanto's enforcement of said patent agreements, and China won't enforce them for Monsanto, just themselves.
In the last decade, Monsanto has been vigorously researching Terminator II technology, a technology intended to isolate the terminator gene in the variety it is placed and prevent it's spread to legacy crops in the field. They may not be successful.
At this point I will offer the belief that this will eventually be highly damaging to Monsanto's profitability, which is why I predicted that the market would destroy Monsanto, and I recommended Monsanto use the technology.
Currently the US and Canadian courts have been friendly to Monsanto's efforts, however Monsanto is a crony capitalist corporation, and crony capitalist is only a nice way of saying Fascist and Fascism takes it's self down in the end.
Court decisions may change and they certainly won't become more friendly toward Monsanto outside the US and Canada, making things more difficult for Monsanto.
Without going on too long, I also have to stipulate your concern, that it is possible that Monsanto will corner the world seed market before they crash.
