I remember too, back then when people were still (rightfully) mad at the concept of binding a game to a drm system that was account-based.
I also remember the days before steam, were there was no online account on an arbitrary site forcefully linked to your purchase just to play that offline game, and were the best copy-protection was the slow internet speed. Now THOSE were the days.
I've gotten tired of the double-standard were people would on one hand happily feed their children games where they can outright slaughter hundreds of peoples in a shitton of ways, but would go into berserk mode once even the tiniest speck of naked skin shines through. The rating system exists for a reason. There's no reason to keep a platform like steam exclusive to a certain type of mature/adult games (in my opinion).
On the topic, it seems to makes it easier for commercial games to get on steam, so I guess it's a good thing?
