There was a bit of a scandal when they started merging their Chinese OS with their American OS. I think they were called Hydrogen and Oxygen. I haven't used a OnePlus phone since then so I'm not totally sure what their software is like nowadays.
I'd rather not support a Chinese company, but since no one else will sell a phone with descent specs with a microsd card, I'm going to be forced into it sooner or later. My n20 ultra is still doing fantastic for now, though.
If you're willing to pay a lot of money, Sony might be an option. They have kept the micro SD card on their phones. There are rumours they'll start updating their phones longer with the VI series too but we'll have to wait and see.
If it makes you feel better, many components in smartphones are already made in China. The country already has a great degree of control if they wish to exercise it from a supply chain attack perspective.
My point is, you’re not leaping from zero to suddenly they are in your supply chain. They already were in your supply chain to some extent.
Well yeah. Who hasn't committed heinous war crimes or some genocides? If no other shit corporation will give an option that is so obviously a benefit to the consumer, then I'll choose the manufacturer from the current evil country. Not like it's better to buy an iPhone that's been made in China.
