Ah, thank you for confirming that, I didn't think about looking at Blockstack's FAQ itself. But then I reiterate my question: what does the blockchain enable here exactly? TFA says that it's "exciting for crypto[currencies]" but it just seems like a cloud computing framework that happens to use ethereum for purchases.

Just to be clear I'm not saying it's useless, actually being able to host your own data anywhere you want and having "end-to-end" encryption sounds great, I just don't see the "blockchain is going to revolutionize the world" angle.

Part of the problem here is that we are still in the infrastructure phase of blockchain development, so most dapps still rely on multiple centralized services. But as the infrastructure develops that will shift. For example, (i) all of the blockchains are working on scaling, (ii) Sia, Filecoin and a few others are working on blockchain based storage systems, (iii) Maker Dai, Basecoin and others are working on a stable coin, (iv) 0x and others are working on decentralized exchanges without custodians, (v) many are working on making addressed and key management easier, (vi) distributed identity verification and 'user trust' systems are developing, etc. All of that will take time, but as systems develop, more complex and more truly distributed dapps will be enabled.
