It really does perplex me that the iCloud website is as bad as it is. I'd almost think it was abandoned-ware except that Apple continues to update it. Their whole cloud offering (iTunes store, Apple Music, iCloud) needs a MASSIVE overhaul. Everything should be available via the web and on a modern accessible website.

I'd go as far as to say that they need a new point-person in charge of their Cloud Services because whoever is doing it now is completely out of touch. iTunes in particular is embarrassing, and I personally buy less stuff because I don't want to run it (instead use Vudu, Amazon Digital, etc).

iirc, icloud was written in sproutcore. version 2 of sproutcoure became ember which is now in version 3. there was no upgrade path from sproutcore 1 to ember, so likely its a case of needing a rewrite and that not being prioritized.
