there needs to be more traditional unicorns (the ones on the right) in media than "modern" unicorns
not only do they seem more interesting and original, but i'm sure you can get a "modern" unicorn by just attaching a horn on a horse's [fore]head. not to mention, like another person here said - they are just more whimsical 🥰
I guess it has to do with the rise of live-action fantasy. in animation you can draw them as fantastical as you like but in live-action you kinda just have to stick that ice cream cone on that horse, unless you're gonna do it with CGI which comes with its own problems
