It's still a very valid complaint, and will forever be as long as you're tied to Steam's server being up and willing to give you the content you paid for. That may not always be the case, for example if financial embargos prevent Valve from actually providing the service in your country. It's more like you're paying Steam to use their service rather than actually buying the game. Right now people are not worried about Steam exit scamming and thanking us for all the fish, because it's a very solid service that has considerable resilience and just keeps getting better and better, and even managed to release the Steam Deck which seemed like an impossible dream some years ago. But there's a nonzero chance they can just ... close. Which was a very real possibility when they launched. Now, not so much.
