When I save things to Google Drive, my data could legally be snooped on in three ways:
1. My national government, by court order or sketchy secret court order.
2. Google, who are in the business of tracking and profiling.
3. The US government, by court order or sketchy secret court order.
A person might hope cloud storage provided by a national government would reduce the snooping by two thirds.
Of course, that analysis ignores risks like the service getting hacked, my account getting hacked, and suchlike - which some would say are much bigger risks.
As an enthusiast I of course make encrypted on-site backups, which I then protect by syncing to a cloud provider, and I protect the encryption secrets with a password manager, and protect the password manager and cloud accounts with a U2F key, and protect the U2F key with two spare U2F keys in off-site secure locations.
I can understand, though, that most of the population doesn't want such complexity, and prefers to be able to reset forgotten passwords without losing their data.
Treating your cloud provider as an hostile adversary is a useful security advice, through I would personally prefer to not give a hostile adversary my data in the first place.
I was late to reply but this question is good. Here's the answer why I do not trust my country and trust foreign countries. No offense please, it is just my thoughts and personal opinion after years if being treated well by my own government.
Imagine this: You are a US citizen, and during COVID your kid gets a rash on their ass. You take a photo and send it to the doctor via some google service. Then google flags it, reports you to the police, and now you're in "the game", even though you did nothing wrong and were a responsible parent.
Same thing but if you had used a chinese service like Tencent (i do not know what they have as apps), nobody would care what medical images you're sending. So, who’s actually the bigger risk to your privacy and security?
And this is only the basic use case. Now imagine you're a drug dealer and you want to host your blog post explaining what experiments you did in your basement with different compounds. I guess north korean hosting companies will be your best bet.
And also I am pretty sure the opposite direction works as well, if you want to say that your president looks like a certain animated character, better use some US or EU company that have no business interests in your country.
