The article is about use in an enterprise. An enterprise runs professional/enterprise/ltsc versions which do NOT steer you to the cloud - what data sovereignty concerns have you seen in those editions of windows/server? They've gone through a lot of pains to ensure those concerns are taken care of for enterprises/governments so i'm curious the ones you think they missed.
You can make the argument for their consumer editions sure, but that's a different product with different features, different price point for different users.
Win 10 and 11 are steering you to cloud first, out of the box. That's fine if you like it, but I don't and quite a lot of my customers don't.
The real problem is about data sovereignty. I'm a Brit and ... MS isn't.
