Wow, this is awful. Some people reported that these ads are also very petty and not necessarily related to the game, like apparently Elden Ring shows an ad for a licensed mousepad when you hover over the game now…
Edit: Playstation Product Manager says this is actually a new bug. I really doubt it but they do seem to be “fixing it”.
It was nice to have someone take this stand and I fully support this. People switching over to Linux already have their own stuff to deal with and need time to accustom to their new environment, and forcing them to embibe ‘FOSS’ philosophy and other strong opinions as held by others in Linux communities is only going to turn them off.
