that is the root of the trouble, the pre-crypto legal concept of 
"processing" (e.g. in EU and CoE108) subsumes storage+computing, and 
legal control doesn't pass to a mere "data processor" even if has 
capability to read and disclose data to a foreign jurisdiction

The power of compulsion in e.g. FISA 702 is over a service provider to 
(effectively) backdoor their running stack. Authors of the OS or lower 
in the stack are not in that "service provider" firing line (and an 
unremarked amendment in FISA 702 in 2008 extended the scope beyond 
telcos/ISPs to Cloud providers)
