I have never bought a single game on Steam for this exact reason. I will buy from any game store except Steam.
The service on Steam is nothing superior over others. For people that want privacy but can live with DRM, I like Heroic open source launcher for playing games on both Epic and GOG, but Heroic does have issues launching Fortnite.
Why are you mentioning Linux? I did not. Keeping this all with the context of using Windows, both Epic and GOG stores provide API access which proves they only want to compete but Steam demands tyrannical control and tell gamers want they are allowed to do while Steam maintains the right to erase a user's game library without a refund.
Steam does and has deleted ganes from people's library without giving refunds. People have developed a blind allegience to Steam either through ignorance or lower cognitive function, but Steam is between aburden and a plaque on PC gaming.
Did you read the court documents in the video? The simple fact that Epic allows API proves that they not tracking and datamining people's information.
I have never bought a game on Steam. I will never buy game on Steam. It was a court ruling that made Steam change their user agreement, not Steam trying to be nice.
