I'm pretty uncomfortable with how many smartphones I'd like to buy end up being Chinese owned companies. I wish Fairphone had a better camera, if it did, I'd just buy one of those and call it day.
What non Chinese manufacture are you looking at? I liked Xperia I for being made in Japan but it’s still Chinese components underneath and as you say there’s no control of all the code.
There’s always Bunnie’s Precursor phone if anyone is interested in commercially developing something reasonably secure and auditable.
I also think it's easy to underestimate your footprint when it comes to ecosystems that involve money in any capacity. No Amazon, Steam, no card information on a Netflix app, no signing in to Google to read a NYT article.
I think either you care about these things categorically or you don't, and I don't think anybody is going to be in the middle space you seem to be envisioning, which is concerned enough about the risks to avoid all banking but still a casual enough attitude about a compromised phone that you're fine with it for uses you consider non-secure.
2. I know it's whataboutism, but from the perspective of a non-US consumer, it doesn't exactly make a difference which country exactly spies on me. I use a Chinese web browser because it covers all my use cases and I don't see a problem with that.
From a latin american POV, it is same-ish as USA manufacturers, they're also tracking everything we do to sell us more unneeded stuff.
The difference is that chinese government is just trying to sell stuff, while USA government is trying to convert all the southern continent into a colony to impose governments and suck up minerals in the meantime. If you ask me if I trust more China or USA, at least China's intentions are clear and direct.
Of course, you people will always have the argument of "national interest" which for us (at least tech-literate people) that's no argument, but still you will find some bootlickers in the mobs.
That part is assumed, and the whole argument unravels once its established that the assumption doesn't hold. And then either the tankies show up, or everyone forgets about it until the next thread where the process plays out again.
At this point I might as well code a messaging app called the honest spy.
Honest spy emails transcripts of all your conversations straight to the law enforcement in your jurisdiction.
