They do change the source IP from the perspective of the host receiving your connection.
But there’s an important difference here. Sometimes you want the IP address to look like it’s coming from a different location because of region locking. Eg Netflix.
Other times you want the origin IP hiding along the data stream to stop snoopers. eg the government.
So changing your IP from the perspective of the receiver isn’t much use if you’re trying to hide from the government. People who are not very tech savvy may not necessarily realize this important distinction until it’s too late. So it’s best to explain the difference.
If you’re routing internet traffic via the VPN tunnel then yes of course that’s true.
But you can be connected to a VPN and only direct specific subnets (like the traditional office network example) to it. You’re not always forced to use it as a default route (using the term loosely here).
That’s pedantry that serves zero purpose to the story. It’s an article for layman, and the only reason to even bring up a VPN is to mention Apple listening to the Kremlin. It serves little to no narrative purpose.
Maybe it is pedantry, but people writing for the general public should explain things well. Why didn’t they just write:
As a result, anyone wanting to access blocked sites from Russia is forced to use a VPN that encrypts internet traffic and makes it appear to come from outside Russia.
This way you’re not lying and saying a VPN “changes your IP address” which is both not accurate nor easily digestible for the general public. That part specifically is what gets me.
