Okay this thread has received some editing and pruning due to the escalating nature of the replies and the definitive over prospective claims.
While it is understandable to have some concerns, especially since the UK looked to break Apples advanced protection. Where enough pressure is brought to bear this can be reversed as it has been there.
Also while some nations have taken to placing embargos on trade with specific companies, users have and continue to find ways of importing devices such as Huawei and Pixel devices in territories where they aren't officially supported.
So while hypothetically the discussion has merits for the forseeable future this does not appear to be a major concern for us as the devices can/will be retailed like Pixels in an umaltered GrapheneOS free state as required.
I will leave the discussion alone for now but if it devolves again it will be locked.
