The ones I’ve seen are deliberate attempts to use the seeds without paying.
Yes, I know. Re-read my last sentence.
Ok, again, no one is forcing these farmers to use the seeds. They have every opportunity to use their own heirloom seeds that they can replant forever, but they don’t because even when paying for seeds the GMO ones bring in more money. It’s a business, if they want to use them they need to pay. It’s ok to fundamentally disagree with seeds as a service but recognize (as the courts did) that this applies to all IP. Just owning a product doesn’t give you the right to duplicate and redistribute it.
