It's extremely stupid. It's the same as all the Monsanto controversies. You aren't allowed (bc of IP law somehow) to replant seeds grown from Monsanto copyrighted strains. If your crop is found to contain any monsanto genetics (they'vesued unsuccessfully for accidental cross pollination, but basically if you just save seeds) then part of your crop/sales proceeds can be seized by monsanto.

People look at this and legitimately think to themselves "yep, markets sure are efficient" when you literally can't grow plants from seeds you own without having to give massive corporations a cut.
