Yes, that does sound silly when read out of context; while they do provide hosting for Sandstorm-aware applications, Sandstorm as a platform allows you to just as easily host your apps yourself (of course, not everyone is technically qualified to setup a VPS and all that jazz). Regardless of who you have hosting your apps (perhaps yourself), you could trivially export your data and move elsewhere - kind of like how if one of my company owned laptops is about to fail, I can always copy my stuff over to one of my own laptops and keep running - I don't have to purchase completely new software and try to finagle my data exports into the new programs. If you haven't already done so, I highly recommend watching the video from the IndieGoGo campaign:
From their index page: "When you use a web app today, you usually connect to its developers' servers. This is backwards, and leaves them in control."
