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.
