The Flower thing led to some people being called transmisogynistic because they referred to Flower as a girl. Of course, Flower really was a girl canonically, so they were treated unfairly. It also led to people assuming that Vocaloid was more progressive than it is.

However, I don't think this was an issue of headcanon. Some people really believed she was non-binary because of that misconstrued quote. I don't think many people were trying to force their headcanon on others, they just genuinely believed she really was non-binary. The moral of the story is to always check your facts carefully. (*´・ｖ・)

I personally think it's fine to headcanon any Vocaloid as non-binary, just so long as it isn't spread as canon. :D
