I think the thing that you are missing is that DRM is a key feature required by game publishers. Games is the main use of the platform and the reason it exists.

I think the thing that you are missing is that DRM is a key feature required by game publishers. Games is the main use of the platform and the reason it exists. Selling a Linux box isn't. One can argue that selling a Linux box at a loss is a dumb idea. One can argue doing so helped super computing to the masses and was a good gesture. However when the reason the box is subsidized is threatened then it's pretty rational to remove the thing threatening it. This was definitely a lesser of 2 evils for Sony business choice. They misjudged how much people cared about Linux. As others have misjudged other ads like no man's sky.
