Google also outsources SWEs. My friend in Mexico worked as this. They have an acronym for this kind of worker, I can't remember. But for example, they contract out work to SWEs at https://www.epam.com.
Not contradicting your point really, just a note
TVC
Yes! Can't believe I forgot. He was an interesting guy - a biologist who was deported to Mexico after living in the US since childhood without citizenship, and then tried working in a lab in Mexico, but the pay was so bad he learned to code and eventually became a TVC.
Extremely cool individual who I miss. Maybe I should say hi to him.
