I hated it in the early days because I wanted to own physical media for my games, etc., and I just didn't trust an online games library that could vanish in a business deal or bankruptcy. Little did I know that CDs and DVDs have a shelf life. I learned to love Steam over the years.
Now I hate subscriptions-for-everything and love Steam even more for only charging me once to buy a game.
My colleague (late 40s) is still like that. Buys only GoG or I guess physical, although it's mostly codes nowadays anyway? I mean good for him but he misses out on like 80% of games.
I don't think Steam will ever die but I hope it won't fall into enshittification at some point.
This is my fear. Gabe won't last forever, and I don't know anyone else who has a customer centric approach as he does. Maybe that guy from Costco who threatened to kill someone over the hot dog price.
