That’s dreadful! I had assumed that iCloud (rather than Dropbox) sharing would share the original as that is already in the cloud anyway. It would just be a pointer or DB entry
I was horrified when I learned that Google wasn’t going to save full resolution by default. Had no idea Apple would do something similar.
That's what I thought myself, but then I realized pictures put into shared albums are actually copied - you can delete the original and it's still available in the shared album, at 0 cost to your iCloud storage.
It's kind of a nice feature, but at the same time it makes doing things like collecting photos from my wife for a photo book annoying.
