People need to realize that you do not own the games that you buy from stores such as Ubisoft and Steam. You are renting these games at best. These companies can deny access to your games at any time they see fit. Whether it’s deleting inactive accounts, a change of policy, business going bankrupt or any act of god.
This is why I only buy games from stores such as GOG or itch.io where I actually receive a DRM-free copy of the game. It’s mine forever so long as I back it up; which is not hard to do since storage is so cheap nowadays.
There is no certainty in flesh except death.
