> the OS will only communicate with publicly signed versions of the server for example
This hardly increases security, and does not increase privacy at all. If anything it provides Apple with an excuse that they will throw at you when you ask "why can't I configure my iOS device to use my servers instead of yours?" , which is one of the few ways to actually increase privacy.
This type of BS should be enough to realize that all this talk of "privacy" is just for the show, but alas...
Before you write off their claims I encourage you to read more about the detailed specifics (if you have the technical footing and inclination to do so). While the approaches should certainly be probed and audited, itβs clearly more than performative. https://security.apple.com/blog/private-cloud-compute/
I don't know what your argument was going to be if I said "no", but in any case, the answer is yes, you can. You can even entirelly uninstall Google Assistant and replace it with your own software, and you do not lose any functionality of the device nor require access to private hooks to do that. I do that myself.
