I wonder if you really even need to hack the console. It might be easier to, say, subvert Rockstar's supply chain to put some code in the next GTA that spent a few cycles doing whatever botnets need to be doing.
They literally had a hard line in the sand. $600. If it costs more than $600 to hack it then they really don't care.
The other big thing is games being locked to a specific OS version, meaning some games require updates to play them. This has been key in their security strategy. It's basically pointless to hack it, it will be patched and you'll have to opt in to the patch to play anything new.
TPM designs that protect against such an attack will become a commodity reducing the cost to include it onto a console. Every desktop, phone, laptop, tablet, microwave, fridge, server, etc will all need TPMs. The demand and scale exists for this to become cheap over time.
