I did buy a lot of the Sony games on Steam despite owning them on my ps5 as well. I got TLOU Part 1 and Part 2, Uncharted 4 and Ghost of Tsushima on both platforms because I like those games and wanted to support more future PC releases so that those games could be preserved forever. But I guess that went out the window and now future PlayStation titles will forever be locked on dead platforms one day.
