companies like Google make an effort to store foreign users' data in foreign data-centers owned and operated by foreign subsidiaries.

Can confirm that while working on the EU rollout for Office 365 a few years ago, this was certainly the case. EU customer data had to stay in Ireland, and there were even rules/debates about how much of the 'metadata' (i.e. to answer "does this user exist?") that could come back to the US.

At the time the reasoning was for EU Privacy Directive and not explicitly based on US law or precedents, but I bet a few realized the alignment and ensured the engineers stayed on this path.
