Living things shouldn't be copyrighted tbh. Neither should food. Plants often being both, but always the first one at least.

Most are specially bred to produce specific styles of fresh produce, like bananas, but this was the first company I'd heard of that removed the ability to propagate. (Aside from seedless stuff like watermelon/grapes) You can go to Japan and get one of the hundred dollar strawberries and you could technically keep the seeds. Lettuce, onion, garlic, tomatoes, peppers, berries, bananas, ginger, potatoes, corn; almost everything can grow from leftover cooking scraps. Plants are resilient.

Chopping the top off, is capitalism at its worst. I can understand not allowing another company to sell the genetically modified produce, but cutting off the top lowers the shelf life and makes it impossible to re-grow. It's pure greed... especially when it can take 3+ years for a pineapple to produce more fruit.
