the placed orders will not just be for bitcoin mining machines. they produce hardware for other industries.
You don't actually believe that, do you?
On their website, they list these 4 industries before bitcoin mining:
Computational research
Medical imaging
Packet integrity verification
Generic fingerprinting engine
On their driver page, they have what appear to be valid download links. You ever tried clicking on them? There is no such software that uses their hardware in any way.
