That’s not how the enforce security works. You’re either capable to secure the device without removing basic functionality, or don’t.
Xbox has a browser, as any iphone/ipad out of there. If the only way for Sony to keep security is cripple functionality; it doesn’t mark their device as valuable at all
(additionally, with proper web browser support you can play web videogames without have to pay Sony: would you say this also apply to Sony’s choice to remove web browser?)
