It's not locked down at all, it's just that the included software and attendant cloud is for pay. You can just as well SSH into device (the password is available on settings screen), copy stuff yourself or install a daemon that will backup files or whatever.
Just remember to ensure you have some form of recovery prepared or make the necessary pogo connector just in case.
Does that just require some hacking, or do they still some how lock that down even if you are a power user?
