That's the biggest problem I have with consoles. They're essentially expensive boxes that are tied to a single service, in this case PSN.
You don't like their store pricing, DRM or other policies? Yeah, well, unlucky. Sell your box and buy a different one (or don't). Too expensive to play online on PSN? Well unlucky, because that's the only way to play online. If it's more expensive tomorrow, you better pay if you want online play or you'll be locked out.
Xbox now locks out uncertified controllers, maybe PlayStation as well? Even their own previous controllers (DualShock 4) don't support playing PS5 games on PS5, so if you want to play a 4 player couch coop game you better own 4 controllers specific to that one console. I get it, the new controller has some new features like "adaptive triggers" - but that's entirely optional. Heck, you can play the PS5 games ported to PC with a DualShock 4 on a PC/Steam Deck.
