If you don’t retain some kind of actual ownership, they will not be allowed to use terms like “buy” or “purchase” on the store page button. I hope there aren’t huge holes in this that allow bad actors to get around it, but I certainly loathe the fact that there’s no real way to buy a movie or TV show digitally. Not really.
EDIT: On re-reading it, there may be huge holes in it. Like if they just “clearly tell you” how little you’re getting when you buy it, they can still say “buy” and “purchase”.
How do you host an Artifact server?
How do we update it to work on unsupported (read future) systems?
You got me on the first one. Artifact is definitely an exception to what I said.
As for the 2nd question, you emulate old systems.
