Heh, I subpoena'd Microsoft once in part of some FOIA litigation I did against the White House OMB back in 2017. They, in no unclear terms, denied it. We were seeking documentation.

I realize it's not a court order, but just want to add to the stack that there are examples of them being requested to provide something within the public's interest in a legal context (a FOIA lawsuit) where their counsel pushed back by saying no.
