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”.
The good thing is that Linux is officially becoming a market space that they have to pay attention to or lose money. Not because of us, but steam deck normalized it. 4% of users doesn’t sound like a lot, but to a company who is desperate enough to put ads everywhere just to make a few pennies, well, it may be worth it now
