The same way I know someone who says "Them immigrants just steals our jobs" is ignorant and racist. Put it this way: there is a slim chance he's paying Bay Area wages and treating his employees well, but odds are he's just paying a bit more than the regional median or average and treats his workers like disposable tissues besides.

You're ignorant for making up a narrative the commenter never put forth.

Also, I think it's odd that you consider regional median and average wages to be exploitive.

If the regional median and average wages are a result of economic depression and politically poor conditions it's hardly a stretch to call it exploitative.

And even if he did tell us how much he paid them, none of us are qualified to determine what wage rate is “exploitation”.

They said "A fraction of the cost," and knowing a little bit about how much developers in Russia get payed, that's probably about 30,000$ per year. Hopefully someone else will chime in with how that compares to the cost of living.
