Microsoft and Sony have successfully prevented their systems from being jtaged or mod-chipped. Not sure you can prevent dumping the actual game binary on the internet. That has lots of software and hardware attack vectors and only needs to be done once by a professional enthusiast.
The game binaries are encrypted, sure you can image the Blurays and put them online but they won't do anyone much good without access to the keys buried in the firmware, which are also a moving target since they can be rotated via mandatory firmware updates if they get compromised. In the case of the Switch, you also have to contend with the proprietary carts requiring a crypto handshake before they'll let you even read the encrypted game data.
What on earth do you mean? How does a physical blu-ray’s encryption keys get rotated?
Do you mean that the protection on the firmware gets refreshed with updates, but the secret it protects always stays the same?

MSFT largely did this by building the xbox platform basically on a local hyper-v system that they can control and not have to worry about hardware.
