The part of that argument I have trouble with is the “until all oven manufacturer were into the game” part. Do you have an example where an entire class of computer hardware became impossible to buy without firmware restrictions? This alarm bell has been sounded as “The War on General Purpose Computing” for over a decade for different pieces of hardware (laptops, desktops, routers, phones, etc.) but it still hasn’t really trended negatively (phones and routers in particular have many more unlocked options today that they did in the early 2000s), let alone come close to extinction for any of them. The broadest category you could make a case for is specifically x86 processors, but only the IME/PSP/SMM components.
I think the reality is there just isn’t as much business incentive to do these kind of things to computing devices as much as people imagine, and instead the arguments tend to paint the would-be oppressors as cartoon villains that want to remove these abilities from the world just because. Android phones that can root or at least sideload have been numerous forever; somehow nobody has bothered to create a halfway serious Google Play Store competitor anyway. Why would every business move to quash something which ultimately isn’t a universal threat? What Epic wants isn’t sideloading or rooting their way on to iPhones, they want Apple themselves to have to let users install Epic’s store through normal channels.
Game consoles, right? Back in the day things like the Commodore were often sold as game systems and computers (the NES wasn’t but you could still run unlicensed software). Nowadays, good luck running something on your PS4/Switch that the company didn’t approve (unless you have a hackable switch I guess, but that’s extremely fiddly).
The NES could not run unlicensed software. In fact, the NES arguably invented the App Store licensing model. Every console (save for the toploaders) has a lockout chip that resets the CPU every second or so unless it's able to exchange encrypted data with a companion lockout chip in the cartridge. Nintendo used this to "protect" the US gaming market from games they didn't approve of.
Technically, the Family Computer (Famicom) could run unlicensed software. It even had a BASIC interpreter and a keyboard controller. Nintendo realized their mistake very quickly, however, which is why the NES has a lockout chip and the disk add-on for the Famicom also locked out third-party disks. (Note that part of the system was the ability to buy blank disks and pay to download games onto them via a Disk Writer kiosk, hence why the disks were proprietary, not just the games.) A number of game developers in Japan found that to be a bit of a shock, from what I've heard.
That’s a good point, but the incentives there make more sense: game piracy has been a huge issue for publishers on every gaming platform (PC included) that didn’t put serious hardware roadblocks to it. They also sell the hardware at a loss, which means locking it down if you don’t want someone to build a supercomputer out of it on your dime.
In my opinion there is an important difference between purpose-built entertainment devices like consoles where sometimes HW cost is donated by the manufacturer and a multi-functional generic computer like laptop/desktop and partly smartphone. I care less about locked PS4 ecosystem than smartphonrs and computers.
