Earlier quoted context omitted.
Doesn't DRM-free literally mean that you get a full local installation without any reliance on online licensing or any other digital restrictions?
You still need to download it. There are plenty of situations in which you might not have downloaded it yet or might have lost/deleted your copy, knowing you can download it again. Also, I think the DRM people are referring to here is the kind that consists of rootkits, monitoring software and similar or, in simple cases, refuses to run or gives you some kind of penalty when it detects certain other software.
I don’t expect any guarantees from digital goods being stored for free in a digital warehouse, unfortunately many do. One doesn’t own the nebulous copy on the distributor’s server, they own whatever copies they downloaded.
