In my opinion when I buy a game on Steam then Steam is the first party launcher for me.

Doesn’t matter if the game is developed/published by EA, Rockstar, Ubisoft, or whatever.

I’m paying money to Steam, I’m getting game files from Steam, that makes it first party launcher.

Other companies are taking advantage of their role as developer/publisher to insert their own launcher to force me to create an account on their service.

But on Reddit (🤮) I see people calling Steam as third party launcher.

Am I wrong or redditors are wrong?
