I left a comment on the video and the poster had the audacity to respond that Malus domestica (which is actually a hybrid complex rather than a true species) is a very homogenous group as justification for using the term “applecrab” to distinguish these smaller ones instead of just calling them crabapples like they’ve always been called. I’m honestly a bit taken aback. Their response did read very well and I could see it easily convincing some people. I would hope that most people on this forum grasp how incredibly variable domestic apples are though. Anything but homogenous.
I probably shouldn’t pick this as the hill that I will die on, but I can’t help myself sometimes.
