USA is being horrible at the moment, but China has a LOT of convincing to do before I’ll let them deliberately have my data.
Best way remains to raise as high a digital moat against everyone. If you need a smartphone, get a Pixel, install Graphene on it and as few apps as possible.
I don’t know to what extent they smuggle data out of the devices, but afaik a de-googlified phone such as Pixel + GrapheneOS gets you close.
