Nope. You're not the only one. I am ok with the ability to delete from all devices, and the cloud, I need to be able to control who can do that.
Without that ability, you will never be able to get rid of pictures you don't want. But I don't want someone else in my family inadvertently deleting all of our photos either. So some type of permissions would help.
We also use apple devices at the preschool we own. Teachers take pictures in all the rooms, photostream gets them to the office computer where they are stored for school use. Once they are copied to the office Mac, they can be deleted off the device. Works well.
But it is somewhat manual to have to periodically clean off each device when they fill up.
iCloud Photo Library sounds like a solution, but it would allow any employee to delete any photo ever taken.
Not good.
So for home, I would like the ability to not see a photo on my device, without deleting it from the library.
At work, I would like the ability (within restrictions) to dis-allow photo deleting from the library.
