I use a Huawei matebook D14 as my personal device. Its primary use is in a WiFi-network (as in 99% of the time). Since I also use MS devices in the same network I log all IPs being accessed from my network ( https://www.raspberrypi.org/documentation/configuration/wire... ) I'll leave the log results of accessed IPs as an exercise to the reader. Hint: no chinese/russian IP addresses are being accessed. I'd guess a lot…
As Snowden revealed, the NSA itself is way above that playing field. They (quite unsurprisingly) use IPs in the respective country, or just false-flag IPs in "enemy" countries. And the data is not actually sent as plain packets but tacked in the form of metadata onto normal, innocent packets going elsewhere. Then servers on intermediate hops exfiltrate that data. And none of it might happen if you're not actually targeted.
That of course underlines your main point. I don't see "sends nothing to foreign IPs" as an argument though.
