It doesn't need anyone to convince devs to implement it. I can do it whenever I run an emulator of old console games already, and devs of those games never implemented it.
If Sony wants to add it as a hardware feature they can.
As far as the patent, hopefully it'll get denied but I doubt it. Once they have it it'll cost someone time and money to challenge it, even though it should be a slam dunk that it is neither a new idea nor innovative and novel. This is how a lot of these egregious parents continue to stand - the cost of challenging them is high, especially if some blistering idiot of a judge ruled in a farcical manner.
That gives a false picture since it only counts legal declared spending.
For instance, what's the effective value to Trump's campaign of Elon Musk buying Twitter and using it to explicitly promote right wing views? How much did Russia spend this time to promote Trump? What about Israel, cause I'll wager Netanyahu prefers having Trump in office, since Kamala might've demanded at least some holding back.
Actual spending to promote Republican and right wingers was way higher.
