I mean yeah, but there is still a browser in the PS5. It's a requirement for things like modern payment methods.
Once you have access to it, redirecting it to wherever you want to go isn't too hard to do, even without a URL bar. You can set up a local DNS server to take you where you want to go, no matter what URL the console is actually trying to access.
Meaning they've done basically nothing to close this exploit venue off.
That sucks ass... Well, even if Twitter support goes down, you can still use the PS5 browser with some DNS trickery. It works the same as on the Switch.
I think it was used as a discord workaround (at least for chat, not voice) as well as a way to do picture in picture of YouTube or other streaming services so you could multitask.
