The berry comic raises a good point that I haven’t seen raised in this thread. Rigorously categorizing berries in a general context could lead to confusion, since the technical and lay definitions are very different.
I don’t see the potential for the same sort of confusion by categorizing fungi as distinct from plants. Doing so doesn’t change the mix of items in the categories, it just establishes that what was considered one category is now considered two.
If the two choices are equally harmless and one is correct in more circumstances, I’d choose the option that is more often correct. For me, continuing to call fungus plants would be rejecting science in favor of tradition.
That’s an odd choice in an article praising a scientific advancement. Of course it’s really marketing and they’re probably trying to appeal to people that think “mushrooms are gross.” Again, doesn’t seem like a great reason to reject the science to me.
Edit: immediately on submitting, I realized I just attempted to categorize categorization problems, so maybe just ignore me
