Even if the "Digital Monstrosities and Corruption Act" doesn't stifle this, then "PROTECT Imaginary Property, Promote Intellectual Monopoly, and other purposes" one probably will.

In Sony's case, this is even more of an insult because it criminalizes a user for restoring features that it was advertised to have in the first place."
