Steam hasn’t been popular for 20 years, my dude. 20 years ago, Steam was LOATHED. I’m not gonna google it because I’m at work, but you can find a gif of the Steam logo performing anal on a bent-over dude.
10-15 years ago it was still fairly common to avoid Steam on purpose. I personally started using it actively maybe 6-7 years ago, but I’ve been gaming for just a bit over 20.
