PS3.
Disabling Linux, as I remember it, basically instantly got it jailbroken.
Suddenly not just pirates out to save/make money, but hobbyists too, wanted to break it.

(I imagine, I don't have any info to suggest they actually had to literally jailbreak their PS3s in order to build their supercomputer, but just making a jab)
If it's good enough for the USAF, it should be good enough for hobbyists to have a go around with it!
Sony typically sells consoles at a loss and makes profits from the game sales. The likes of USAF, researchers, and other companies were buying PS3s in bulk, and using OtherOS functionality without utilizing the primary use of PS3s: games. Often these projects didn't need any GPU power, and OtherOS had nearly full access to the CPU (iirc it had access to the main PPE and 7 out of 8 SPEs). Thus, Sony likely was not making enough money from the consoles USAF et al. bought.
I enjoyed many hours of gaming on the PS2 and I bought it (in part) because I would be able to install Linux on it. I still managed to become a Linux guy today, in spite of the rug by Sony, and I suppose there's nothing overtly wrong with clarifying with an update that the primary intended use of your product is in fact its primary intended use, but as a hobbyist (dang it, now I've gone and done that again)...
My guess is that they don't want to say the quiet part out loud: i.e. they took away OtherOS because they weren't getting the tariff exemptions they wanted and they don't actually want people using these devices for non-royalty-bearing activities (e.g. piracy and homebrew).
There are also several publicly available tools that can be used to pop printers, and use them for other bad things, but it's not an area I have spent much time in other than from a blue team/IR perspective. Printers, like alot of other hardware, are usually poorly maintained, but at least patching has mostly gotten easier and most infrastructure scanning tools will report vulnerabilities and weaknesses in them now.
The USAF also has Kubernetes in F-22s from what I understand now
Every business I have ever worked at has either been built almost exclusively on Open Source software, or a bank that ran almost exclusively on Microsoft.
We're not just pirates and hobbyists!
If pirates managed to get from Linux to pirate copies running, then that's not the same exploit as getting from no-Linux to Linux.
If it were, then there would be no point in Sony blocking Linux.
So the no-Linux to "full" surely must have been invented post-Linuxblock?
