Completely agree. 99%+ of what we call “strains” wouldn’t be recognized under legal definitions. Even still, if you don’t sell the seeds you made, then legally, there’s even less ground to stand on.
IMO if you sell seeds, you should first accept that a “gentlemen’s agreement” is about the only protection you’re going to get. If you don’t like those terms, you should probably find another business to operate in, because there’s really not much else protecting your business.
That said, to me subcool always came off as very protective of his stuff. I’d personally just as soon respect his wishes and let him take it to the grave.
