I support your position and the right to repair, but that’s not the origin of the term jailbreak in the context of computing.
The term jailbreaking predates its modern understanding relating to smartphones, and dates back to the introduction of “protected modes” in early 80s CPU designs such as the intel 80286.
With the introduction of protected mode it became possible for programs to run in isolated memory spaces where they are unable to impact other programs running on the same CPU. These programs were said to be running “in a jail” that limited their access to the rest of the computer. A software exploit that allowed a program running inside the “jail” to gain root access / run code outside of protected mode was a “jailbreak”.
The first “jailbreak” for iOS allowed users to run software applications outside of protected modes and instead run in the kernel.
But as is common for the English language, jailbreak became to be synonymous with freedom from manufacture imposed limits and now has this additional definition.
Thanks for the history and technical explanation. I didn't mean to imply that was the origin (for computing) and was only talking about a specific usage of the word.
I think most people say it to refer to manufacture imposed limits but I wanted to promote a broader usage. That using proprietary software is like being in a jail because your software freedoms are denied.
Oooo healthy online discourse. Where's my popcorn...
Lemmy is such a rad place, I love it here
