My nextcloud calendar doesn’t seem to have a category color, only color per sync account. I’ll look to see if there’s a plug-in, as I’m somewhat interested as well.
I would bet there’s also a bug report somewhere with such a request.
I won’t be able to test iOS easily (the rest of the family have them, but they don’t release them easily).
You’re right, but it’s more nuanced than that.
The EU is like a Hydra. Some heads are consumer facing, others are population control facing.
Success would mean distracting the control heads while wooing the population heads.
No easy task.
