I think that one of the reasons they (frontier companies and the gov) will be putting so much effort into curtailing bugs and vulnerabilities is to limit the blast radius of future AI models. Imagine with the new Sol Ultrafast, they could have pwned Hugging Face in 6 hours and not 4 days (IIRC).

It also seems likely to me that the US Gov. probably already has routine mechanisms for compelling targeted software updates for persons of interest, so I'm not sure that a more formalized backdoor than automatic updates is going to be surfaced in the mainstream, unless that is avenue is also cut down somehow.
