I don't think it matters. If Azure is challenging AWS, Azure is challenging AWS. Who the buyers are is irrelevant; HNer dollars don't double when you deposit them in your bank.
It's obvious companies want to increase H1-B for hiring top talent at lower salaries.
An amazing programmer in India or China probably makes 1/10th of what he would make in America, but they don't know this. They'll be recruited to America on H1-B but they won't contend their salary, they'll be happy making 2x or 3x their previous salary, even if it's 45k/year. Their ability to negotiate salary will be further hindered by a strong possibility of poor-English skills, therefore inability to communicate well.
