Not to shit on other people's work, but I can't help to think that all this effort breeding cultivars of (very invasive) European blackberries could've been better spent further domesticating native species that indigenous peoples have often already partially domesticated. In fact some already exist.
Shouldn't we be focusing on plants that aren't a constant threat to native ecosystems?
