In my testament I’ll share my GOG account data and password in all social networks and Wikipedia with a hand with extended middle finger out of the grave.
Maybe some generations later in the future it becomes suspicious. Valve want gain money and there is no reason that it will deep investigate if the downloads are still paid from the same account and paid with the same banc account, irrelevant if it’s from a different IP or ISP, that are things that can change even with the same user (transladet to other city, changing provider or PC, etc).
In my mobile I use only games from F-Droid (puzzles, boardgames) for in between. My wife use Eternium, a free single player RPG old school (Optional cosmetic buys in the game menu, no Pay2Win), very nice on Mobile (Gesture driven) and PC (Mouse, keyboard), infinite gameplay. In the stores and in Steam
