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”.
I don’t know, it’s a bit hard to assume this was an accident and just a poorly implemented feature. It does cover the screen with the most recent news post, but that’s often an ad, and even on first-party titles like Horizon it just covers the screen with a giant ad for the upcoming lego horizon.
At best it was a feature to shove game news into everyone’s face with no way to turn it off.
