icloud photo sharing need some improvement it is very important, like improve stream video quality play in 1080 resolution, second thing is when we received video trough icloud Photo Sharing we can't save video in mobile, why ? we want to save video in iPhone
iPhone 6s Plus, iOS 9.3.2
You need to ask Apple questions liek "Why" and you need to contact them re suggestions - http://www.apple.com/feedback/photos.html
ICPS is well defined and it is what it is until people request changes adn Apple makes them
My personal guess is since Apple does not charge for ICPS storage they set the sizes to control usage
