PS5 Linux loader goes public, turning console into full Linux gaming PC

> Users who want to downgrade or sideload a specific firmware version can do so using Sony's official reinstall process with the correct PUP file.

this is not true, you can only upgrade using a PUP not downgrade.

Super excited for this, havent been involved since the bd-jb exploit and finally i can use my ps5 the way i want to.

Genuine question, no snark intended, bc this is interesting... but:

Why would someone want to do this? What is the benefit (besides satisfying a technical challenge)?
