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”.
There’s a full screen advertisment for Spiderman Across the Spiderverse when the person is trying to play Spiderman Miles Morales.
The poorly designed feature itself isn’t about showing ads, it’s just showing the top item of the news feed. The news feed can have ads, depending on what the developer publishes to it, which is why I never scroll down to that section.
