When I weigh the choice of handing over my personal videos to a company that is explicitly and actively going to use them to:
train and improve their massive corporate AI tools
develop their targeted ad platform (which is their real product)
build a comprehensive profile about me and my family
Or
Putting a NAS at a friends house, or paying a couple bucks a month for some block storage.
I end up preferring the second set of options. It's fine if you don't, but don't pretend you have no idea that your personal videos and information are valuable to Google.
That wasn't a comprehensive list, just 2 off the jump.
So no, the simpler answer is that sanctions simply aren't a factor. They didn't list every country on the planet.
