We can have both: Ms has Azure Ad - a new/refined open standard that provided sane caching/off-line use should allow self-host on-premise, in cloud as well as Saas/IaaS - add in a new coda-like fs (also optionally as a service) - and I'm pretty sure people would throw some money at it. Imagine having a box running a lan-local cache/node for a few tb of cloud-backup disk - network mounted as /home/$user and/or / - with local machine cache and regular mirroring to the cloud? With the added bonus of being open - making pure self-host an option as well as moving to other vendors?
