Great. Explain to your technically illiterate parents, friends and neighbors how to implement DynDNS, how to poke holes in their firewall, and how to implement a web-based TLS-using file server.
The point of these devices is that a lay person can plug it in to their home network, put in a username and password, then access their 4TB drive anywhere on the world.
I'd suggest that people that technically inept probably don't need 24/7 around-the-world access to those files on their own internet connected storage system. Four terabytes? What would be making up all these gigs that they need to be able to get this easily all the time. Whatever files they need access to that way they could probably fit on a thumb drive -- they wouldn't even have to worry about an Internet provider working properly then. And even if this is a cloud-access-is-a-must issue, Dropbox or a dozen other service providers could fill in just as well with something run in a professional hosting environment.
The kind of people you're talking about leave their broadband modems on the floor under desks for months with static electricity and dust. They mount equipment in cabinets with no ventilation (and no access at all when something stops working sometimes), and bypass the Windows scandisk when it triggers itself (because it takes so long~). Do these sound like folks who should be hosting their own servers?
I feel if you want to host your own node on the Net, you learn how. And if you don't want to learn how, you let someone else host it. A half-assed "I bought this but can't even tell what plugs go where unless I call support" solution isn't doing you any favors.
