Sony:

Is this even legal? EU legal?

I foresee a future of jail broken PlayStations

To be fair, that future is now. People are already hacking PS5's to turn them into Linux machines

They've longed lobbied for anti-circumvention legislation and the corrupt politicians in the US and the rest of the World (with the EU Comission as a notable mention) have made sure it was implemented everywhere, exactly to avoid such a future.

The entire rotten edifice of Intellectual Property in the present day is literally the product of decades of corrupt politicians stealing more and more from the Public Domain to extend and protect this entirelly artificial kind of "property" for the benefit of the ultra-rich - as Digital became more and more important, laws were made or changed to take more and more rights away from common people in order to make the wealthy wealthier, which is why the richest people in the world right now are mainly in Tech.

I was there in the 90s when this corrupt destruction of the "commons" started limiting what could be done in the Digital domain and saw how we Techies lost that war, which is how we ended up with two decades of every more and ever more enshittified "closed garden" setups for all kinds of digital things.

Without shit like anti-circumvention legislation run of the mill people would have easy access in their friendly corner store to China-made devices doing things like what you describe or, for example, break your iPhone out of Apple's closed garden.

The shit low-innovation (certainly when compared to the 90s) World we live in right now is the product of decades of this purposeful transforming of the digital and intellectual commons into a Feudal system.

I agree that discs are outdated and can't hold enough data for the whole game and they should turn to cartridges.

Not on a Sony platform.

We just need to return to these bad boys.

The console market has ceded market share to PC over the past few decades specifically because a growing portion of the market sees that it's cheaper over time. Everyone knows about Steam sales being better than the equivalent on consoles, whether they know it's because of increased market competition or not. More and more people have shown that they're doing the math on subscriptions to play online and realizing that it's not a good deal. When you cut out the physical market and its own methods of keeping purchase prices down, more people still will do the math and decide not to engage.
