You don't think WhatsApp for some reason stopping to work and airlines losing their default way to issue tickets is a national security issue? How about health care appointments with national ID and address on them being sent as PDFs and stored on Meta's servers? All of those are massive national security issues for me. It can grind the country to a halt for days on end.
There's a reason South Korea has laws requiring all data on its citizens and geography to be stored in Korea. Even Google Maps doesn't quite work in Korea.
South Korea is not a great example here. It's been weeks since the big data center fire and they've barely started to recover. Storing all data internally can really backfire if best practices aren't being followed, and that's a lot more likely with a not-invented-here approach.
