I don't get it - if you were aggressively sourcing for months, presumably advertising your job via normal channels, wouldn't that already satisfy the requirement for perm?
I keep seeing annecdotes about exceptional one of a kind talent, world class PhDs etc. I think we can all agree that majority of H1Bs we work with are not those people. They are regular devs without exceptional skills (not saying no skills, just nothing especially unique). There are thousands laid of, qualified US workers that can fill those roles. You can't convince me that we have such lack of talent in tech today that massive amounts of h1bs have to be brought in.
"Zuckerberg owns or controls 88.1% of Facebook’s Class B shares, which each have 10 votes at the annual meeting — 3.98 billion votes overall. There are only 2.4 billion Class A shares, which are the only shares ordinary investors can buy. So any proposal Zuckerberg doesn’t like will fail by nearly a 2-1 margin, assuming all Class A investors vote together, which never happens. (Zuckerberg owns 0.5% of the Class A shares.)"
Clearly all throughout the funding rounds he made sure he controlled the shares that mattered.
