The original CPU design was purchased from the US, but a variety of chip makers have been improving on the design in a variety of ways, so it is not US cloned, but is US descended - rather distantly descended by now.
according to the interwebz, your system is ARM based and in addition ARM is vulnerable to spectre. how many vulnerabilities like spectre affect the "US design"?
The Orange Pi Cpu does not do speculative execution, therefore is not vulnerable to spectre.
I think some ARM processors do? Not sure if the arm core that allwinner chip uses does though. Anyway, the SoC probably uses so called 'intellectual property' from different designers including americunt ones. And there are other components on the board of course. Point being, it seems hard, even for the chinese govt, to know for sure that the system isn't backdoored by many of the western scum 'players' in the 'industry'.
