I guess ask the Romans about half of those.
The last time I saw a TIL about this sort of thing though it turned out that “Aluminum” was the original but some academics thought “Aluminium” sounded fancier. My understanding is that it relates to the oxide names, which in the case of aluminum is alumina, after which the -a is swapped for the -um, similar to how magnesium oxide is magnesia. But I’m too lazy to fact check.
Also Molybdenum exists too, so it’s not like Aluminum would be the one exception that is just -um and not -ium.
I am trying to think of scenarios where this will screw with normal users because companies never do moves like this unless they’re after some sort of grift.
But I am not seeing it at present. Maybe I’m just too tired and my brain isn’t working, but if a game is downloaded digitally and the license comes with it, there’s effectively no difference. Take it offline, you still have the license, no issues.
The only potential impact I can think of is if you have two users on a console that is the home console for neither person, and both of them bought the same game digitally. User 1 downloads the game, the license comes with it, and they take the console offline. User 2 then uses the console, tries to play the game they own, and gets a license error because the console is offline and doesn’t know they own it and therefore it can only be played by the person who downloaded it. But I think that’s how it works already, since User 2 would still need the console to be online to import their licenses.
