I always felt a little queasy installing a .kext from some random foreign-language websites (be it FTDI, or Alfa drivers, or even RealTek updates). I can feel the bias in me, "Oh no, this must be bad because it's foreign," which is absurd, but I still shouldn't be asked to sudo something when I buy offbrand hardware.
Huh. My bias runs so deep that I somehow misremembered a Chinese-language document from FTDI, which I guess I made up in my mind. Unless like some companies their drivers are done in their Taiwan office. It quite common for multinational companies to distribute projects to different sites.
