I see no moral issue with a company protecting its intellectual property. Research is not cheap, and no one would be willing to invest the millions it takes to develop a new product if they did not have the legal protection of patents.
What's the best way to control the world? Control the food supply.
The food supply is not, and has never been, controlled by seed companies in a highly competitive market. Food supplies are controlled by politicians. Whenever you see people starving, look at the government: Venezuela, the USSR, China, any number of African despotic countries--the story is always the same. The politicians control the food distribution, and the people starve.
Furthermore, the fact that seed companies sell purposely non-propagatable seeds to large scale farmers does not prevent you from buying true-breeding "heirloom" seeds. There are seed companies that specialize in those, too. May I suggest Johnny's seeds?
Exactly. Mass starvation is caused mainly by food distribution, not availability, especially when a government is in control of the distribution.
It is the single most devastating weapon in the socialist/Communist arsenal, and has killed more people in the 20th Century than all of the wars fought in that era combined.
