There seems to be confusion around what this specific decision is for.
This is not about foreign emails stored in foreign servers by Google. This is about US emails that Google decided to store outside the US. Why do that? I'm guessing Google has developed technologies like Spanner [1] that distribute data on a global scale, to help with capacity, disaster recovery etc. Even for data generated in the US and accessed in the US by US persons.
So if you have a US person's emails shipped outside the US by Google for no other reason other than Google's convenience, do US warrants still apply to the foreign-stored data? It's not a simple question.
The Microsoft Ireland case doesn't seem relevant as the person in that case was a non US person. Or, to be more specific, the Ireland datacenter that MSFT was running was meant for non US email accounts.
Overall, the US law seems to offer sufficient protection to non-US person with data stored outside the US. This specific decision is not about that.
