What operating systems, stacks, languages, compilers, etc do they use?
But yeah if the point is just to use non-US tech they could run Ubuntu Linux (SA) or OpenBSD (Canada) or I suppose Red Flag Linux (China). Language wise...maybe Python or PHP or Erlang or an ML language?
If they just meant the last piece of physical hardware sold by an American headquartered company, then I guess that's something?
Also, whats in those Lenovo boxes? Godson chips or American Intels? They are absolutely not running Windows on any desktop then I assume?
