It can't easily be plumbed in, though. I can spin up my own Linux build with none of that plumbing and do what I want with it. I can grab China's best models and use them or distilled versions on my own terms because OSS allows for that. Until hardware comes fully locked down and the models cannot be run on old hardware, both a long ways off, OSS is a way out.
In the not so distant future, all your coding edits (for work anyway) will be through centralized gateways. Think remote desktop environment where pasting from the client is disabled.
Politicians can act very quickly if there is good enough "incentive".
Linux will be an illegal operating system in 2027 because it doesn't do age verification.
