From my understanding, what's explained there with a lost of unnecessary buzz words is operating system linked to a blockchain that will allow or not your operations, based on your account level and how much you paid for using that OS.
That's imho an unnecessary use for blockchain.
* If it's a proper (public, decentralized) PoW blockchain, I don't want to wait for a new block to be mined to allow me start calc.exe (and I won't even discuss about who is paying the miners for the job!)
* If it's a private blockchain, a simple database would have been faster.
Imagine running a Linux OS or Windows OS for browsing that's actually Decentralised.
Well, the internet is more or less decentralized even now and you can browse it.
If you can't wait until Microsoft will charge you for every move of your mouse... all I'd say is that you have strange tastes.
If you can't wait until your smartphone will record on blockchain, forever, everything you do on the phone, .. well, I've said it already.
TL;DR; Imho that's not the proper/normal/expected use for a blockchain; as @BlackHatCoiner correctly said it, blockchain is just a special database.
