Vendor-lock is quite high, possibly higher in the US.
Look at iPhone, hardware is behind, restricted, unauditable privacy and questionable software in terms of performance (especially starting iOS 26, where you lost the choice for Liquid Glass).
Impossible to reasonably sync AirPods or watches, Macbook or choose the firmware version.
In comparison, the irony is that China offers the freedom (like with Qwen).
On these supposedly evil Chinese devices (phones, headphones, watches, etc), you have an open platform with great hardware, that you can modify as much as you want, and the only people who restrict you is... Google (making sure you cannot root without losing to important apps, so technically you can root, but practically you can't).
All the claims about "China = bad hardware and bad software" were true 20 years ago, but this is not the case anymore.
That being said, should certainly be quite cautious about default setup... you have US surveillance, PLUS, Chinese surveillance.
